The Story of D-ONLY: Our Lab Diamond Hong Kong Brand

In recent years, the lab diamond HK market has surged in popularity, becoming a favourite among many consumers for various jewelry applications. Some may ask: "What is the difference between a lab grown diamond in Hong Kong when compared with a natural diamond?" As our lab grown diamond Hong Kong have learned, both share the exact same chemical composition and physical properties.

The only difference is that natural diamonds take over a billion years to form deep underground, whereas a lab made diamond is formed sustainably in a laboratory environment. It takes approximately a few weeks to cultivate a lab grown diamond, also known as a lab diamond. Beyond being crafted into stunning lab made diamond jewelry, they can also be created in various colors, making them visually captivating. At D-Only, we offer a wide range of lab grown diamond HK jewelry with unique designs, where you are sure to find your perfect piece!

Traditional Craftsmanship + Modern Management:Achieving Quality Lab Made Diamond HK Jewelry Pieces

When discussing different types of diamonds, including lab grown diamonds in Hong Kong, a question often arises: What constitutes true "jewelry"? Is it the pursuit of luxury brand names, or a return to the essence of the jewelry itself? Which path represents the pursuit of quality, craftsmanship, and rationality?

As third-generation jewelers, who have grown up in a jewelry family and worked in the retail sector for 13 years, we have a different answer to this question. Here is an introduction to our lab grown diamond Hong Kong brand, and a sharing of our values regarding jewelry. We want to tell you the story of D-Only's birth and why we chose lab diamonds as our primary medium.

Before We Talk About Lab Diamonds in HK:From Grader to Third-Generation Jeweler

My journey with lab made diamonds in HK, and jewelry as a whole, began under a microscope. Thirteen years ago, when I first completed my diamond grading course, my view of diamonds was purely academic. Before the advent of lab grown diamonds in the Hong Kong market, I was obsessed with the 4Cs standards and fixated on the proportions of every facet. As the third generation of a family in the jewelry business, I grew up under the influence of "old-school jewelers". In that era, designing and making jewelry was a slow and rigorous process.

This "influence" is deeply imprinted in my DNA, and how we work with lab diamonds in HK today. In 2015, we opened our first showroom. We were full of passion, accumulated loyal clients, and witnessed countless happy moments. However, as time passed, both the market and customers changed. Terms like "cost-performance ratio", "eye-clean", and "buy a Rolex instead of a diamond" began to appear frequently.

The Dilemma of a Small Brand:The Beginning of a Focus on Lab Made Diamonds

In 2020, we moved into iSQUARE in Tsim Sha Tsui. Commercially, this seemed like a milestone. However, it was in this brightly-lit core business district that I deeply felt the pain points of small retail brands in the lab diamond Hong Kong market context.

In Hong Kong, retail rents and constantly rising costs act like an invisible knife, slowly slicing away our survival space. In the supply chain of traditional natural diamond retailers, when you spend a large budget on a piece of jewelry, a significant portion of the profit is actually paying for the mall's rent and the brand's advertising fees!

This caused a great internal struggle. As a jeweler educated from a young age to value "quality first", I noticed that to maintain price competitiveness and interest from customers, various "compromises" began to be made by other jewelers in the market, such as lowering color standards, accepting visible inclusions, or slightly sacrificing gold weight. This was not the kind of jewelry business I wanted, nor the experience I wanted to bring to my guests.

In October of last year, we made a bold decision: to officially rebrand and establish D-Only, blazing a new trail in the direction of lab made diamond HK jewelry.

The Birth of D-Only:Developing The Lab Grown Diamond Hong Kong Market

We named our lab diamond Hong Kong jewelry brand "D-Only," a very direct statement. Everyone who understands and loves diamonds knows that in grading standards, “D” Color represents the highest level of "colorless". It is the purest, brightest specification for a lab diamond in HK and internationally, and the undeniable standard for the older generation when buying diamonds.

But behind this name lies a deeper meaning: our target audience — clients looking for lab diamonds in HK, as well as international lab grown diamonds — are people who share our values. They are fellow enthusiasts who appreciate and demand the beauty of high-quality jewelry and are unwilling to make "downgrade" compromises for the sake of budget.

In the past, people bought jewelry considering only the best: color had to be D/E, clarity VS or even VVS and above. But today, the high price of natural diamonds makes these standards unreachable for many. We do not want these standards to disappear even when working with lab made diamonds in HK. Instead, we wish to showcase our persistence: we are determined not to compromise on mediocre quality and constantly seek progress at all levels, actively promoting the international and lab grown diamond HK markets.

Technology Restoring Tradition:Why is Lab Grown Diamond Hong Kong Jewelry Embrace?

It is this determination that turned our gaze towards lab made diamonds, and the constant innovation in lab grown diamond technology. With the help of modern technology, the lab diamond Hong Kong market allows us to turn "top-tier" into "the norm”. At D-Only, we no longer need to convince lab made diamond customers to accept yellowish hues, nor do we need to turn a blind eye to inclusions! In the realm of lab grown diamonds in Hong Kong, pursuing D color and VS+ clarity is no longer a sky-high luxury, but an accessible one.

Requirements for Lab Made Diamond Jewelry:Reflecting Our Core Values

In operating our lab made diamond jewelry business, we adhere to the following principles:

1. Traditional Craftsmanship:

We insist on using the most rigorous "old-school" eye to screen every single lab diamond and finished product.

2. Modern Management:

We utilize technology to lower the costs of lab diamonds in HK as well as jewelry, removing unnecessary expenses.

3. Reasonable Pricing:

When customers purchase a lab grown diamond or product, we let the price return to the value of the jewelry itself.

This is the core vision of D-Only: to use modern technology to restore the soul of traditional craftsmanship, and bring this high-quality lab made diamond Hong Kong experience to every consumer at a reasonable price. As a third-generation jeweler, I believe that persistence in the quality of lab diamond HK jewelry and sincerity towards guests will never go out of style. This is why when you see our lab grown diamond jewelry, you may find that they possess the same soul as those treasured heirlooms of the past. We believe that a lab made diamond is worth owning!

Breaking Myths &Technical Truth About Lab Grown Diamonds in HK

The Difference Between "Simulants" & "Synthetics":

Many customers contacting us for the first time about lab grown diamonds in HK often have a look of curiosity and scepticism in their eyes. They usually ask: "Honestly, do these lab made diamond pieces look different from real ones? Can any inherent difference be detected?"

In the field of professional gemology, we have 2 very strict definitions for non-natural stones: “Simulants” and “Synthetics”. These two words sound similar, but they are worlds apart in chemical essence:

Simulants: Only "Looks Like" It Common stones on the market like CZ (Cubic Zirconia) and Moissanite belong to the “Simulants” class. They merely mimic the appearance of a lab diamond. For example, CZ has a hardness of only 8.5 and will scratch and fog over time; Moissanite is silicon carbide, and although hard enough, it has a "double refraction" phenomenon under a loupe, making the fire look too colorful and dazzling, lacking the noble texture of a diamond. Let alone being a lab grown diamond, chemically, they are not diamonds at all!  
Synthetics: Ideally Diamond in Essence These are what we in the industry call “Synthetic Diamonds”, now commonly known as “lab grown diamonds”, or even shorter as “lab diamonds”. Its chemical composition is exactly the same as a natural diamond—pure carbon. The crystal structure is the same, the refractive index (2.42) is the same, and the hardness (10) is the same. It is like "ice from a freezer" versus "ice from Antarctica". A lab diamond Hong Kong stone and a natural diamond are essentially the same substance, just from different birthplaces.  

Lab Diamonds vs. Natural Stones:Equally Brilliant, Indistinguishable to the Naked Eye

To help our clients understand how consistent lab made diamonds in Hong Kong and natural diamonds are visually, I often use a simple example: Suppose I place two diamonds in front of you now. One is a natural mined D Color, VVS2 clarity, and the other is a lab made diamond stone of D Color, VVS2 clarity. Both the natural and lab diamonds have undergone the same standard of cutting and polishing, and their brilliance is identical. Now, if I ask 1,000 people to guess which one is natural, what would be the result? Statistics tell us that about 500 people would guess correctly! Why? Is it because they have good eyes? No, it is purely a matter of probability. It's like flipping a coin; the chance of guessing right is 50/50. This means that even experts, without the aid of professional instruments, cannot distinguish the difference between a lab diamond Hong Kong stone, and a natural diamond with the naked eye. This is why visually, lab diamond HK products have achieved a quality equal to natural diamonds.

While the difference between the two types of diamonds cannot be distinguished by the naked eye, as a responsible merchant, we must be honest: although a lab made diamond looks identical, modern professional instruments can indeed distinguish between them. Traditional thermal conductivity pens cannot detect the difference, because the physical thermal conductivity of a lab diamond and a natural one is consistent. However, more modern handheld spectrometers can distinguish whether a stone is natural or a lab grown diamond in Hong Kong, by detecting the crystal growth structure or trace elements.

The 2 Main Technologies for Producing Lab Made Diamonds in Hong Kong

Having confirmed the material, let's introduce the 2 main technologies used for producing lab grown diamonds in HK: HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition). We don't need to be scientists, but understanding the technical characteristics of these two types of lab grown diamonds can help you ultimately choose better jewelry or products:

1st Lab Diamond HK Production Technology -HPHT (High Pressure High Temperature):

This lab made diamond HK production technology simulates the high-pressure environment deep within the earth's crust. Its advantage is the ability to create lab grown diamonds in Hong Kong with very white colors (High Color). However, limited by technology and physical conditions, it is difficult for HPHT to grow larger crystals. Therefore, in the lab diamond Hong Kong market, we commonly see HPHT used to make lab diamond melee stones, as well as main stones under two carats.

2nd Lab Diamond HK Production Technology -CVD (Chemical Vapor Deposition):

This technology is like 3D printing for making lab grown diamonds, allowing carbon atoms to stack layer by layer in a vacuum chamber. CVD is not limited by the size of the pressure chamber and is very suitable for growing large carat crystals. This is why the 3-carat, 4-carat, or even larger lab made diamonds you see now mostly originate from CVD technology.

At D-Only, we utilize the advantages of the lab made diamond HK supply chain to combine the coverage of both: using CVD for transparent large main stones, and HPHT for smaller main stones and melee stones.

Choosing Lab Grown Diamond Hong Kong Pieces:Returning to the Joy of Wearing Jewelry

At D-Only, we have observed a very interesting phenomenon: our customers, especially the mature demographic between 35 and 55 years old, have undergone a huge shift in their consumption motives over the past few years, increasingly choosing lab diamond HK pieces.

From "Showing Others" to "Pleasing Oneself":

Since the COVID pandemic, the pace of the world seems to have slowed down in many aspects. We have reduced large-scale social engagements and spent more time with ourselves or our families. In my opinion, this shift has also deeply affected jewelry consumption views regarding lab diamonds in HK: previously when buying jewelry, many people would think: "What will others think when they see this diamond?" But now, our customers more often say: "As long as I am happy looking at it, I’ll go ahead and wear it."

This is an awakening of "self-satisfaction". People are beginning to realize that wearing jewelry, whether it’s made with lab grown diamonds in Hong Kong or using natural stones, shouldn't be about meeting others' expectations or displaying financial power. The reason the lab made diamond Hong Kong market attracts so many veteran buyers is precisely because it fits this current mindset. I don't need to prove to anyone how much this stone is worth; I just need to look down, see its beauty, and feel that pure joy of wearing it. Therefore, one could say that lab diamond HK jewelry perfectly caters to the mindset and needs of today's consumers.

Not for Investment, Emphasising Ease of Wearing:

There is also a relatively recent market trend that must be mentioned: a few years ago, we experienced a wave of crazy luxury investment fever, such as watches or certain brand-name handbags being hyped to sky-high prices. But as the bubble burst and prices corrected, many began to reflect: if buying luxury goods is for investment, can you really enjoy the process of using them? When a piece of jewelry becomes an asset, you have a psychological burden wearing it — fear of scratches, and fear of depreciation. This defeats the purpose of jewelry as an accessory. At D-Only, we have no prejudice against natural diamonds; we even respect the rarity and historical value of natural stones. But we find that more and more customers who originally owned natural diamonds are turning to purchase lab grown diamond jewelry. Why has their requirement shifted to lab grown diamonds in HK? Because they "don't care" anymore!

They don't care if the stone was dug from the ground or grown in a lab, because they have passed the age of needing jewelry labels to define their worth. For our clients, lab made diamonds offer a more “relaxed” type of luxury. You can wear a lab grown diamond piece while traveling, exercising, or living your daily life without being overly cautious. This is exactly the freedom brought by lab grown diamonds in Hong Kong. Perhaps this psychological unbinding is what modern jewelry lovers truly seek for.

The Liberation of Daily Wear:Jewelry Shouldn't Be Locked in a Safe

This shift in mindset has directly driven the popularity of lab grown diamonds in HK for daily wear. Previously, if you owned a natural diamond necklace worth hundreds or thousands of dollars, you probably only dared to wear it to weddings or important dinners, but locking it in a safe on most days.

But now, having chosen lab made diamond jewelry, and with prices returning to a reasonable range, everyone can finally wear their jewelry out with peace of mind. This is the experience D-Only lab diamond HK jewelry wants to bring you: beloved pieces should be part of life, not a high-and-mighty offering.

Professional Craftsmanship & Exclusive Jewelry Making:Not Just Selling Lab Made Diamonds in Hong Kong

Of course, having a good mindset and good stones is not enough. As a jewelry brand rooted in Hong Kong, we have extremely high requirements for the setting craftsmanship of lab made diamond Hong Kong pieces. Although a lab grown diamond is cheaper than natural ones, our motto is accessible luxury, and the lab diamond is just a vessel. Therefore, throughout the entire production process of our lab grown diamond jewelry, our attitude towards a lab diamond is exactly the same as our attitude towards a natural one worth hundreds of thousands of dollars.

We insist on using experienced local Hong Kong masters or seasoned veterans for the main stone setting. The production of lab made diamond Hong Kong jewelry, from the polishing of prongs to the metal finishing and plating processes, is refined in every detail. We know that our standards must be higher than those of seasoned lab grown diamond jewelry buyers. They buy lab made diamond HK pieces because they chose a different vessel, not because they lowered their aesthetic standards. We hope that when you wear D-Only's lab made diamond HK jewelry, others see not just a high-quality, sparkling diamond, but a piece of craftsmanship that is well-made, warm, and persistent.

Lab Made Diamond Jewelry Sales:Practicing Our Promise

At D-Only, we are not just selling a lab diamond or jewelry piece, we are selling professional service and a long-term promise. Although we have transitioned to an e-commerce model for most of our lab made diamond sales, behind us is a dedicated company that has been deeply cultivating the jewelry industry for 13 years. This represents that we have physical connections, accumulated reputation, and a complete after-sales system for lab grown diamonds in HK and jewelry.

The Challenge of Selecting Lab Made Diamonds:From "Round" to "Fancy"

Many customers ask us: "There are thousands of lab made diamonds online, why should we buy from you?" Because "reading a certificate" and "understanding a lab grown diamond" are two different things! Especially when we are talking about sourcing a non-round, fancy cut lab made diamond or stone, this is a profound art.

If selecting a round lab grown diamond, perhaps looking at the cut data on the certificate gives you an idea. But if it is an oval, pear, or emerald cut fancy shape, you will find that the lab diamond certificate actually tells you very limited information. It won't tell you if this oval diamond has a significant Bow-tie Effect, nor will it tell you if the length-to-width ratio of this lab made diamond is harmonious. Therefore, this requires the rich experience and aesthetic eye of a professional.

Not to mention when we add the variable of colored lab diamonds, or need to find a pair of perfectly matching colored lab grown diamond stones for earrings, the difficulty rises significantly. Even though the supply of lab made diamonds in Hong Kong has increased, finding two lab diamond stones with consistent fire, shape, and color among the masses is still like looking for a needle in a haystack.

The technological progress of lab diamonds in Hong Kong hasn't made this simple; it just turned it from nearly impossible to possible. And at the D-Only lab made diamond brand, our team with 13 years of experience is here to help you realize this possibility! We filter out sub-par lab grown diamonds in HK for you, ensuring that only lab grown diamonds or stones that truly meet D-Only standards appear before you. Because of this "uncompromising" persistence, we have not yet listed colored lab diamond stones in the website's permanent collection, offering them only for bespoke orders. The tonal variables of colored lab grown diamonds are too great, and we do not want to lower standards to fulfill an order, nor do we want to provide lab made diamond jewelry that deviates from your expectations without in-depth communication.

Service from the Heart:Lab Grown Diamond HK Business Well-Received

If you do some research on our D-Only lab grown diamond HK brand and our jewelry, it is not hard to find that a frequent comment from clients is "rapid response". What lab diamond customers fear most is not encountering a problem, but finding no one to help when a problem arises. We must be honest: jewelry is handicraft. No matter how exquisite the craftsmanship, under long-term wear and physical "collisions”, situations like loose main or side lab made diamond Hong Kong stones can happen. This is a physical phenomenon; no one can guarantee it will 100% never happen. But the value of D-Only lies in: We are here, and we will handle it with our best effort and speed.

Our lab diamond brand is a dedicated company with a 13-year history. When you praise our lab grown diamond jewelry products, we are grateful; when you have opinions on lab grown diamond products, or even encounter repair issues, we stand up responsibly to handle them. This attitude of taking responsibility is our due obligation as a responsible lab grown diamond HK retailer, and we will not neglect you or fail to respond just because the transaction is concluded.

About Our Lab Made Diamond HK Jewelry, Ordering Process & Prices - FAQs:

1. Why do I need to wait 2 to 3 weeks for my goods after choosing a suitable lab made diamond at your store?

At D-Only, we are often asked by lab diamond Hong Kong clients: "Why can't I have it immediately? Why wait 2 to 3 weeks?" Firstly, 90% of orders are completed within the first two weeks, and the remaining lab made diamond jewelry is finished within the third week. There are three main reasons behind this arrangement:

Firstly, this is the craftsmanship persistence of semi-custom made products. Many lab diamond shops use generic "public molds" to shorten the production time. But every lab grown diamond, even of the same carat weight, has minute differences in diameter and girdle thickness. We refuse to force your precious lab diamond into an imperfect mold. These 2 to 3 weeks are exactly the process where our craft team meticulously sculpts, including:

  • 3D Adjustments: We fine-tune the CAD drawing of the ring based on the specific lab made diamond you selected to ensure the prongs fit precisely.
  • Exclusive Casting: This step is casting the metal into shape, followed by manual surface finishing by the master.
  • Fine Setting: Ensuring the lab diamond alignment, balance, and security meet standards, and that prongs fit snugly so they don't easily snag on clothes. This makes our lab made diamond Hong Kong jewelry look more refined with smoother lines — because it is "custom-made" for a specific lab diamond.

Secondly, we refuse the risk brought by keeping inventory. In the case of rings, which have the largest sales volume, as an example: if we were to stock ready-made goods, we could usually only stock the generic Hong Kong size 13. If it doesn't fit your finger, it must be resized. We strive to avoid this practice, especially for lab made diamond jewelry styles with side stones. The metal stretching or compression during resizing destroys the structure, leading to deformation of micro-setting prongs and significantly increasing the risk of stone loss later. We insist on producing after receiving the order to ensure the lab grown diamond product precisely fits your finger size upon leaving the factory, requiring absolutely no secondary damage, ensuring the most stable structure. This is also why we do not recommend engagement ring styles that are too complex with side diamonds, as alteration is nearly inevitable.

Thirdly, is the difficulty of maintaining inventory. Even for just one standard design at D-Only, we offer: 4 Main Stone Sizes (1ct, 1.5ct, 2ct, 3ct) 4 Metal Colors (18K White Gold, 18K Yellow Gold, 18K Rose Gold, Platinum) 10+ Ring Sizes Simple multiplication (4X4X10) means over 160 combinations for a single lab diamond jewelry style. If we were to stock ready-made goods for every style in the office, that would be an astronomical inventory volume! Huge inventory means tied-up capital, insurance, and warehousing costs, which would ultimately be transferred to the lab diamond Hong Kong customer. D-Only chooses a "zero inventory" made-to-order model to keep operating costs to a minimum, allowing us to maintain low-cost operations so we can focus on lab grown diamond product design and production without compromising due to operational pressure.

In summary, for this 2 to 3-week waiting period, you get: a setting custom-made for the lab diamond, and a semi/fully custom-made lab grown diamond jewelry piece at a reasonable price. "Expensive jewelry is the piece you don't want to wear because the quality isn't good enough; a high-quality piece of jewelry is value for money because you can't bear to part with it."

2. What actually is a “Lab Made Diamond”?

Lab made diamonds, also known as lab grown diamonds, refers to a diamond created in a laboratory environment using technology that simulates the growth environment of natural diamonds. A lab made diamond in HK is exactly the same as a natural diamond in terms of chemical composition, optical properties, and physical hardness.

3. Is a lab diamond actually a real diamond?

Yes. According to the definition by the US Federal Trade Commission (FTC), a “lab diamond” is in fact considered a diamond. It's like "ice from a river" versus "ice from a refrigerator"; the essence is both ice. A lab diamond is not a simulant like Zircon or Moissanite. Quite the contrary, a lab made diamond is considered authentic.

4. Why are lab made diamond Hong Kong prices so much cheaper than natural ones?

This is because the supply chains for the two are different. Natural diamonds are expensive due to the scarcity of mining, marketing, and monopoly; whereas lab diamond Hong Kong products are products of technology. As technology matures, production costs drop significantly, so the price of lab diamond HK stones are also cheaper. Additionally, D-Only operates through an e-commerce model, saving on expensive store rents, allowing the price of lab made diamond jewelry to return to the product itself, naturally making it more attractive.

5. Can the naked eye distinguish between a lab diamond and a natural one?

Even trained experts cannot distinguish the difference between a lab diamond and a natural one with the naked eye or a loupe alone. Only through professional instrument testing can one distinguish which is a natural one and which is a lab diamond in Hong Kong

6. Can a lab diamond hold its value over the long term?

We believe not. Even the sales process of the past decade does not use value retention as a reason for purchase. If you are pursuing "investment appreciation", we suggest contacting relevant professionals. From our perspective, whether it is a natural diamond or a lab diamond, the recycling price in the second-hand market is usually lower than the retail price. The value of buying lab grown diamonds in HK lies in their use for creating high-quality jewelry, not for resale profit. However, because our lab made diamond jewelry uses only precious metals, the jewelry body itself will retain substantial value even after a long time.

7. Will lab grown diamonds experience changes in their color over time?

The chemical properties of lab grown diamonds are extremely stable. Like natural stones, lab diamonds in HK can maintain their color and luster permanently. What turns yellow or foggy is Cubic Zirconia (CZ) or other low-quality simulants, not a lab diamond in Hong Kong.

8. Does D-Only's lab grown diamond HK jewelry come with certificates?

All main stones from our lab grown diamond HK brand come with IGI (International Gemological Institute) certificates. Why not GIA you ask? Currently, the vast majority of high-quality lab diamond stones on the market are sent to IGI for grading immediately after cutting. Especially since GIA adjusted its grading standards for lab diamonds in October this year, IGI remains the major grading authority in the lab diamond Hong Kong and international markets due to its detailed and stable grading system. To ensure the stability of the lab diamond supply and detailed, transparent grading information, we choose the widely circulated IGI certificate.

9. Where can I buy lab made diamond Hong Kong products with a guarantee and peace of mind?

It is recommended to choose registered merchants with production experience when buying lab made diamond stones or jewelry. A brand like D-Only, with a 13-year jewelry background, can ensure that the lab made diamond Hong Kong products you purchase have guarantees in terms of quality and after-sales service.

10. How should lab grown diamond jewelry be maintained? What cleaning methods are recommended, and which are not?

The safest maintenance and cleaning method is to use warm water and soapy water with a soft toothbrush to gently brush the lab made diamond jewelry. Some people use toothpaste to clean their lab made diamond jewelry, but this method is highly inappropriate because toothpaste contains fine abrasive particles. Although harmless to the lab grown diamond itself, they can cause fine scratches on the metal setting, causing the lab grown diamond jewelry to lose its original lustre. Also, do not use ultrasonic cleaners to clean lab grown diamond jewelry, as the frequent and rapid vibrations of the cleaner may loosen the stones, increasing the risk of the lab made diamond falling out.

11. When talking about lab diamonds in Hong Kong, we often hear “HPHT” and “CVD”. What exactly are they?

  • HPHT and CVD are two technologies for manufacturing lab diamonds in Hong Kong and internationally.
    • HPHT (High Pressure High Temperature): This lab made diamond manufacturing process simulates the extreme environment deep underground, using immense pressure and high temperature to crystallize carbon atoms. It is usually used to manufacture lab made diamonds in HK that are under 2 carats or melee stones. The color of this type of lab diamond is usually extremely white.
    • CVD (Chemical Vapor Deposition): This method of creating lab grown diamonds injects carbon-containing gas into a vacuum chamber, allowing carbon atoms to stack layer by layer like snowflakes. This is not limited by the volume of the pressure chamber, so large-grain lab diamond HK stones over 2 carats on the market mostly belong to this category.

    12. Can I pre-order exclusive lab diamond Hong Kong jewelry?

    Of course, our lab diamond Hong Kong brand offers semi-custom, as well as fully custom, production services to clients. You can first select your favorite lab made diamond in Hong Kong, and then our experienced team will design a unique jewelry style for you. However, such pre-order arrangements usually take longer, so please wait patiently and enjoy the experience of creating your very own lab grown diamond Hong Kong jewelry.

    13. Does a lab diamond have enough hardness?

    The Mohs hardness of a lab diamond in Hong Kong is 10, the hardest substance in nature, exactly the same as a natural diamond. Therefore, they are very suitable for making wedding rings and other lab made diamond HK jewelry that can be worn every day.

    14. How can I distinguish between a “Moissanite” and a “Lab Grown Diamond”?

    Moissanite exhibits a double refraction phenomenon, with fire that is too dazzling, ghosting on facets, and a plastic look. A lab grown diamond is singly refractive with noble brilliance. D-Only only sells true lab made diamond HK products, and never uses terms like "carbon diamond" to confuse our customers.

    15. What if the prongs loosen on the lab grown diamond jewelry bought from D-Only?

    If the above situation occurs, please contact our lab grown diamond HK brand immediately. As a responsible lab grown diamond Hong Kong retailer, we provide comprehensive repair and maintenance services. Professional masters will reinforce and repair it for you, restoring your lab made diamond HK jewelry to its best condition.

    16. Why do some people say lab made diamond Hong Kong products are not environmentally friendly? Is there any truth behind this?

    In fact, within the lab diamond industry, this is quite a controversial topic. Although lab made diamonds avoid the destruction of the earth's surface caused by mining, the production process does require electricity. However, with technological advancements, many producers have begun to use renewable energy when creating lab made diamonds. Overall, the environmental footprint of lab made diamond Hong Kong products is still smaller than traditional mining.

    17. Is it suitable to use a lab diamond in Hong Kong for creating a proposal ring?

    Whether to use a lab diamond in HK, this depends entirely on the values of each couple. We understand that some couples still cherish the traditional meaning of natural diamonds, and we absolutely respect that. However, we also observed that more and more couples are beginning to choose lab diamonds in Hong Kong, mainly because their wedding expenses are huge already as it is, or they hope to allocate more budget for their honeymoon, etc. Therefore, they want to exchange the same or less budget for top-tier visual impact by going with a lab diamond Hong Kong piece. So, there is no right or wrong choice between natural or lab made diamonds in HK; only what suits your values and requirements.

    18. How can I ensure the lab diamond that I receive matches the one described in the certificate?

    Every certified lab diamond has a laser code engraved on its girdle that matches the certificate number, which you can verify with a magnifying glass. To give lab made diamond HK customers more peace of mind, and especially for overseas customers or those choosing free delivery services, we provide extra protection: before the lab grown diamond product ships, we will personally record a verification video and send it to you. The video will clearly show the inspection process of the laser code under a microscope.

    19. Where is the origin of D-Only's lab grown diamonds?

    Although we are a lab diamond HK brand, our supply chain is global. We source the best quality lab grown diamonds and gemstones from all over the world, focusing on quality screening rather than a single origin, though indeed most of our lab made diamond HK stock is sourced from India.
