Lab Grown Diamond

Lab-grown diamonds are synthetic diamonds created under the same conditions as natural diamonds. While natural diamonds form underground over a long period, lab-grown diamonds are produced by replicating that environment in a lab. This difference in the production process is the only distinction. Because they have exactly the same composition and characteristics as natural diamonds, even professional appraisers find them difficult to distinguish. The world is now focusing on this "new era of brilliance" that is reasonable, sustainable, and peaceful.

Difference from Natural Diamonds

Lab-grown diamonds have the same chemical, physical, and optical properties as natural diamonds. Both are composed solely of carbon (C), and values such as hardness, refractive index, and dispersion are all identical to those of natural diamonds. Additionally, like natural diamonds, they can be issued with a certificate (grading report).

Features of Lab-Grown Diamonds

reasonable

Because there are no mining costs and the supply volume is stable, it is cheaper compared to natural diamonds of equivalent quality. In particular, colored diamonds, which have high rarity value, tend to have a significant price difference.

Sustainable

Lab-grown diamonds do not require mining, so they have less impact on the natural environment (soilDesolation · Water Pollution ·It is said that the (carbon dioxide emissions) are small.

NO CONFLICT

Thanks to the Kimberley Process, it has been proven that most diamonds currently traded are not related to conflict. However, lab-grown diamonds are guaranteed to be ethical because their distribution channels are clearer.

How Lab-Grown Diamonds Are Created

There are two methods for producing lab-grown diamonds: the high-pressure high-temperature method and the chemical vapor deposition method.

High Pressure High Temperature Method (HPHT)

The high-pressure high-temperature (HPHT) method artificially recreates the same high-temperature and high-pressure environment found in the mantle where natural diamonds are formed. It generates diamonds by applying a pressure of 55,000 atmospheres and a temperature exceeding 1,400°C to cylindrical carbon. In the past, only small-sized diamonds could be produced, but advances in technology have made it possible to create larger diamonds. Currently, this method is the mainstream technique for producing lab-grown diamonds.

Chemical Vapor Deposition (CVD)

Chemical vapor deposition is a method of growing crystals inside a vacuum chamber at very low pressure. By using a thinly sliced diamond as a seed and applying microwave energy to methane gas containing carbon, diamonds are grown in layers. This technique allows precise control over the type and amount of scientific impurities, enabling control over the size, purity, and color of the resulting diamonds.
