Will Lab Diamonds Pass a Diamond Test?

Lab-grown diamonds are a modern marvel, created using advanced technology to replicate the natural formation of diamonds. Their rising popularity comes with many questions, especially about their ability to pass standard diamond tests. Let's explore how diamond tests work and whether lab-grown diamonds measure up.

Understanding Diamond Tests

What Are Diamond Testers?

A device that ascertains a diamond is a diamond tester, working with measuring the diamond's physical properties mainly through the thermal and electrical conductivities; these are different only in the case of a diamond. Most used kinds are:

Thermal Conductivity Testers: These measure a principle about diamonds dispersing heat better than most substances to be told apart from its simulates.

Electrical Conductivity Testers: These determine if a diamond is a Type IIb diamond, natural diamonds with boron impurities that are conductive. Advanced testers can sometimes distinguish the difference in synthetic diamonds.

What is interesting is that diamond testers were originally created to find cubic zirconia simulants. However, lab-grown and natural diamonds often look identical, so determining if a diamond is one of these often requires advanced testing.

How Diamond Tests Work

Thermal tests check the flow of heat and electricity through the stone. In terms of thermal tests, natural and cultured diamonds are the same because the carbon in both is the same. Cubic zirconia and other simulants break the test because they do not conduct heat as well as diamonds do. Testers give instant results, but these are not failsafe and cannot distinguish between cultured and mined diamonds.

Will Lab-Grown Diamonds Pass?

Thermal Conductivity Test

Lab-grown diamonds pass tests on thermal conductivity because they are chemically and physically identical to mined diamonds. That is to say that, in comparison, their heat-diffusion capabilities are equivalent. The average thermal tester cannot differentiate a mined from a lab-grown diamond but can only identify whether a stone is indeed a diamond.

Electrical Conductivity Test

While natural diamonds can sometimes exhibit electrical conductivity due to trace elements like boron, most lab-grown diamonds, especially those made via Chemical Vapor Deposition (CVD), do not. Advanced electrical tests, however, can sometimes identify these subtle differences, particularly in Type IIa diamonds (which most lab-grown diamonds are). This makes electrical conductivity tests a useful, though limited, tool for gemologists.

Advanced Testing Techniques

Professional gemological labs, such as the Gemological Institute of America (GIA), use spectroscopy, fluorescence analysis, and observation of growth patterns. These methods can identify inclusions or growth patterns unique to lab-grown diamonds, such as metallic inclusions left behind by the High-Pressure High-Temperature (HPHT) process or growth striations from CVD.

A remarkable fact is that more than 98% of natural diamonds are Type Ia (nitrogen-containing), and most of the lab-grown diamonds are Type IIa (nearly nitrogen-free) and, therefore, require special techniques for distinction.

Popular Misconceptions

Many people believe lab-grown diamonds are fake. In fact, that couldn't be further from the truth. Lab-grown diamonds are real diamonds, with identical hardness, refractive index, and brilliance as their mined counterparts. Misconceptions arise through confounding lab-grown diamonds with simulants.

Cubic Zirconia: A popular diamond simulant that fails all thermal and electrical tests because it doesn't have the carbon structure of a diamond.

Moissanite: Moissanite can perfectly imitate the brilliance of a diamond but conducts heat more efficiently than diamonds, causing false positives in some tests. Advanced testers easily detect it.

Lab-grown diamonds are not simulants and substitutes; they are real diamonds, but grown in a laboratory setting.

Practical Tips for Buyers

Buy from Authorized Dealers

Make sure your diamond comes from a reputable jeweler who states if it is lab-grown or not. This is important since inspection and tests in the physical world will not show its origins. Additional certification through legitimate sources may also be required for authentic items.

Ask for Certification

Certifications from institutions such as GIA (Gemological Institute of America) or IGI (International Gemological Institute) are also important. Certificates clearly state whether a diamond is mined or lab-grown along with its specific grading details.

Know Testing Limitation

Basic diamond testers indicate a diamond's authenticity. It does not differentiate between the diamond being natural or lab-grown. Only advanced methods conducted by gemologists determine if a diamond is original or not.

Certified documentation is your most reliable tool for knowing what you're buying. It ensures clarity and confidence in your purchase, whether natural or lab-grown.

Conclusion

Lab-grown diamonds pass most standard diamond tests, such as thermal conductivity checks, as they are chemically and physically identical to natural diamonds. However, distinguishing between lab-grown and mined diamonds demands advanced techniques, which is usually done in professional labs. While lab-grown diamonds may present an ethical and cost-effective alternative to mined stones, learning their origins can go a long way in getting the best deal. Natural or manufactured, the brilliance and beauty of a diamond never go out of style-a true symbol of love and commitment.

Discovering the Beauty of Lab-Grown Diamond Rings

In modern jewelry, lab-grown diamond rings are captivating the hearts of many, offering a blend of sustainability, advanced technology, and timeless beauty. One example that embodies these qualities is the Vintage Inspired Lab-Grown Engagement Ring. This exquisite piece features six pear-shaped lab- grown diamonds at the center, totaling an impressive 4.10 carats, complemented by six round lab- grown diamonds on the sides, adding up to 0.36 carats. Crafted in lustrous 14kt white gold, this ring is not just a symbol of commitment but also a testament to the marvels of modern science in jewelry making.

Vintage Elegance with a Modern Twist:

The allure of vintage lab-grown diamond rings lies in their ability to meld the charm of past eras with contemporary craftsmanship. The featured engagement ring epitomizes this blend with its three-stone setting and round shape. The total weight of the diamonds reaches approximately 4.46 carats, secured in a setting that highlights their clarity (VS) and color (F-G), ensuring that each stone sparkles with unmatched brilliance. This ring, weighing 6.3 grams, promises a significant presence and a comfortable fit, with complimentary sizing available. Lab-Grown Diamonds:

A Sustainable Choice: Lab-grown diamonds like those gracing this vintage-inspired ring offer an eco-friendly alternative to their mined counterparts. Unlike natural diamonds, which require extensive and often disruptive extraction processes, lab-grown diamonds are cultivated in controlled laboratory environments. This lessens the environmental footprint and guarantees a conflict-free source, positioning them as an ethical option for mindful consumers.

How Are Lab-Grown Diamonds Made? Understanding how lab-grown diamonds are created is key to appreciating their value and beauty. Two primary methods are used to produce these gems: Chemical Vapor Deposition (CVD) and High Pressure, High Temperature (HPHT).

CVD Diamonds: This technique entails placing a diamond seed within a chamber saturated with carbon- rich gases. Under high temperatures, these gases crystallize on the diamond seed, allowing it to grow layer by layer. CVD diamonds are known for their purity and ability to pass older diamond testers, which recognize them as natural diamonds due to their carbon content.

HPHT Diamonds: HPHT is a process that mimics the natural formation conditions of diamonds. It involves placing a tiny diamond seed in a carbon-rich environment. Under high pressure and high temperature, the carbon melts and forms a diamond around the seed. Interestingly, due to trace metals in the diamond, HPHT diamonds can sometimes fool testers into misidentifying them as moissanite, a similar gemstone.

Testing the Authenticity: The advancements in technology have been significant when it comes to testing lab-grown diamonds. Modern testers are designed to accurately differentiate between lab-grown and natural diamonds. However, as mentioned, older testers might recognize CVD diamonds as genuine. In contrast, HPHT diamonds could be misidentified due to their composition. This fascinating aspect of lab-grown diamonds highlights the importance of using updated and sophisticated testing equipment to ensure the authenticity and quality of the gemstones.

Metals In Time and Lab-Grown Diamonds: At Metals In Time, the commitment to offering beautifully crafted, ethically sourced, and technologically advanced jewelry shines brightly. The Vintage Inspired Lab-Grown Engagement Ring is just one example of how this retailer is at the forefront of embracing lab-grown diamonds, providing customers with pieces that are not only stunning but also responsible choices for our planet.

Do Lab Created Diamonds Pass a Diamond Tester?

The very first non-natural diamonds were grown by General Electric in December 1954. But, due to the high cost of their creation and low customer demand, they were considered a success for science and not the jewelry industry.

Later, in the 1970s and 1980s, lab created diamonds finally became widely available and desirable to shoppers. However, they weren’t completely identical to the real deal, remaining small and of lower quality than natural stones.

Today, lab diamonds account for 2 to 3% of the market for engagement rings. And, they’re so close to authentic that even the experts sometimes have trouble telling them apart.

So, do lab created diamonds pass a diamond tester?

The simple answer is yes! Keep reading to learn all about this affordable and ethical alternative to mined stones.

What Exactly Are Lab Created Diamonds?

Most lab grown diamonds are created through a process called chemical vapor deposition, or CVD.

This method uses carbon gas to heat a diamond seed (a tiny authentic mined stone) in a sealed chamber. The combination of heat and pressure applied during this process causes carbon molecules to stick to the seed, growing into a larger diamond.

Unlike lab created diamonds of the past, CVD stones have few flaws or inclusions, and are sold in a wide variety of colors, including dazzling bright white.

Because CVD gives scientists great control over the properties of the diamonds that they are growing, it is now possible to produce large, gem-quality stones. And, as CVD requires lower pressure and temperature points than previous diamond production methods, the process is far less costly.

For customers, this adds up to high-quality diamonds at affordable prices. And, you’ll know for certain where your stone came from and how it was sourced.

Can You Tell the Difference Between a Natural Diamond and a Lab Diamond?

No, and neither will anybody else. To the naked eye, lab diamonds look identical to those that took billions of years to form.

They carry all the traditional fire associated with one of the planet’s most precious stones, and you’ll shop for them the same way, using the 4C’s.

Lab diamonds can also be used in all the same settings as mined stones. So, if you’re in the market for the perfect engagement ring, this is an outstanding option that is nearly guaranteed to fit your budget.

Because lab diamonds refract light just as well as natural stones, they’ll look great in a wide variety of settings. They pair perfectly with all shades of gold, and can even be used among mined diamonds for a dramatic effect! For example, as a solitaire set atop a dazzling backdrop of tiny pavé or even micro pavé diamonds.

Laboratory grown diamonds also come in a surprising assortment of exotic colors, including blue, white, and even yellow. These perfectly mimic rare colored diamonds, which are among some of the most sought-after stones on the market.

Do Lab Diamonds Pass a Diamond Tester?

A diamond tester is a hand-held pen that measures thermal and electrical conductivity. The tool’s metal point is applied to the stone that it is testing, and a mild electrical current is passed through it. How quickly this electricity moves through the stone can tell whether or not it is an authentic diamond.

In most cases, today’s lab grown diamonds are so chemically similar to those formed naturally, that the tester cannot distinguish one from the other. In some cases, however, lab diamonds contain less nitrogen than natural diamonds.

A diamond tester will absolutely identify some imitation stones that are not authentic lab created diamonds, such as CZ, or Cubic Zirconia. 

This pen test isn’t the only way that jewelers inspect and assess diamonds. They also use visual clues such as measuring how much light each stone refracts, and how hard its surface is. Examining jewels under magnification can rule out some diamond substitutes like Moissanite, white sapphire, and white topaz. These won’t refract both colored and white light, and they aren’t among the hardest materials on planet earth.

Your jeweler should also be able to locate a natural or lab diamond’s certificate number under their microscope. Replicas like CZ and Moissanite won’t have this.

How To Clean a Lab Created Diamond

Cleaning a lab created diamond is surprisingly similar to cleaning a mined stone. Soak your jewelry in a small dish filled with mild dish soap and warm water for 10-20 minutes. Then, use a soft toothbrush to give it a gentle all-over scrub. This will help to break apart any buildup. Once you’ve thoroughly cleaned your diamonds, rinse them under running water to remove any soap residue.

Cleaning your diamonds at home is easy enough, but you should also take them in for professional care at least once a year. An expert jeweler can perform deep cleaning and repairs that would be impossible to do on your own.
