Lab-grown diamonds: real diamonds with scientific DNA

Wild orchids that grow in valleys are orchids, and orchids that grow in artificial flower houses are also orchids;

The ice cubes formed outdoors in winter are ice cubes, and the ice cubes formed in the refrigerator are also ice cubes.

What about diamonds grown in the laboratory? Laboratory-grown diamonds are grown in the laboratory, but they are also crystals made of pure carbon. The physical, chemical and optical properties are exactly the same as those of mining diamonds. Therefore, laboratory-grown diamonds are real diamonds.

Whether a diamond is a real diamond or a fake diamond is not defined by the market. If the arrangement of carbon atoms is a diamond, then it is a diamond, irrefutable. Whether the source of a diamond is underground or a laboratory is a matter of source, not a definition of true or false.

The natural hue and color grading of white diamonds directly affect the appearance of the diamond. Hydray selects D-G color grade bright white, presenting the high-quality color of diamonds.


Clarity is a measure of the purity and standard of diamonds. Hydray selects FL-VS2 pure diamonds to achieve the brilliance of diamonds.

Lab-Grown Diamond, in simple terms, is a diamond seed that grows into a diamond in the laboratory. By simulating the natural formation environment of mining diamonds in the laboratory, scientists have cultivated gems with the same composition and characteristics as the mining diamonds. In 1963, China's first cultivated fine-grained diamond was born. With the continuous advancement of science and technology, the technology of cultivating diamonds in the laboratory has gradually matured.

1. Select high-quality diamond crystals and put them in a culture dish.

2. Simulate the underground growth environment of traditional mining diamonds in the laboratory. After 200-400 hours of high temperature and high pressure, diamond crystals continue to grow.

3. The grown-up diamond rough, after cutting and polishing, has the same molecular structure, physical properties, and optical effects as the mined diamond.

The cut is very important in 4C. Cutting, polishing, and symmetry are all important criteria for measuring the quality of a diamond. Hydray craftsmen use exquisite craftsmanship and follow the industry's highest cut grade, 3EX high-quality cut diamonds, showing sparkling diamond fire.


Carat is the unit of weight of diamonds. When cutting diamonds, Hydray pays more attention to preserving the sparkle of diamonds and highlighting the brilliance of diamonds as much as possible.

In addition, Hydray selects high-quality TypeⅡa diamonds, which are clear and bright without yellowing, comparable to top D/Flawless flawless diamonds. (Note: Among mining diamonds, Type Ⅱa grade diamonds account for only about 2%, which are very rare. They are very rare because they do not contain or contain very little nitrogen and other substances.)

[Laboratory-grown diamonds also have an "ID card"]

In April 2019, the GIA Gemological Institute of America announced that it would replace "Synthetic Diamond" with the nomenclature of "Laboratory Grown Diamond".

In the report issued by the IGI International Gemological Institute, the term "Laboratory Grown Diamond" is adopted.

Today, GIA, IGI, and HRD, the three major jewelry appraisal institutions in the world, can issue diamond appraisal and grading certificates for laboratory-grown diamonds. All products sold by Hydray are accompanied by an authoritative identification certificate, which supports re-inspection by domestic authoritative institutions.
