Round Raw 3-4CT DEF Color VVS VS SI Clarity HPHT Lab Grown Diamonds
Lab Created Diamonds Description
Lab grown diamond (synthetic diamond) is a kind of diamond crystal synthesized by scientific method to simulate the crystallization conditions and growth environment of natural diamond artificially. Look from the product attributes, lab created diamond and natural diamond are crystals of pure carbon, has exactly the same physical, chemical and optical properties, transparency, refractive index, dispersion, etc as natural diamond, in brightness, luster, color, flashing fire completely the same as the natural diamond jewelry features such as lab grown diamonds and natural diamonds are real diamonds.
HPHT diamond technology is also evolving. HPHT used to focus only on small gem-grade diamonds, but in recent years, many HPHT diamond manufacturing companies have also started to produce large carats, some of them even more than 10 carats.
HPHT diamonds can now be internally purified to VVS grade. The biggest advantage over CVD diamonds is the high color grade, such as HPHT diamonds, many of which can reach DEF(the top three grades of white diamond color).
HPHT used to be grey white, but now it's more DEF standard. But HPHT's adamantine luster is no better than that of CVD diamonds, and adamantine is usually the result of a very high refractive index and good cutting -- it's one of the sharniest shiny transparent stones in the gemstone world. Without a doubt, diamond diamond diamond luster is the best. The diamond-like luster of CVD diamonds is almost as good as that of natural diamonds, while HPHT is slightly inferior. So most of the jewelry industry will use HPHT diamond as a mile stone, because it is very good, color flashing again as small liming-liang shi, is very perfect.
Whether HPTP or CVD diamonds, we are witnessing the maturation of their manufacturing processes.

From a scientific point of view, cultivated diamonds are exactly the same as natural diamonds, the only difference being where they are formed.
