Wholesale HPHT Lab Grown Rough Diamonds
What Is Lab Grown Diamond?
Lab grown diamonds are diamonds cultivated by artificially simulating the crystallization process and conditions of natural diamonds. They are almost the same as natural diamonds in terms of chemical composition, crystal morphology and other chemical and physical properties.
Lab grown diamonds are comparable to natural diamonds in terms of crystal structure integrity, refractive index, relative density, dispersion, etc. In terms of hardness, thermal conductivity, thermal expansion, resistivity, compressibility, etc., the performance of both is almost the same.
What Is HPHT Lab Grown Diamond ?
The high temperature and high pressure (HPHT) method evolved from the catalytic method has become the main method for synthesizing gem-quality diamonds.
The temperature and pressure used in this method are lower than those of the direct method, and the conversion of carbonaceous raw materials to diamond is promoted by adding catalysts such as iron and nickel.
The role of the catalyst is to speed up the synthesis process and reduce the required temperature and pressure.
Lab Grown Diamonds VS
Natural Diamonds
1. Lab grown diamonds have the same composition, physical properties, chemical properties and optical properties as natural diamonds, but they are grown in different environments.
2. In 2018, the US FTC deleted the word natural in natural diamonds, changed it to mineral diamonds, and included lab grown diamonds in the diamond trade.
3. Lab grown diamonds have the same identification system and certificates as natural diamonds
