Lab Grown Diamonds Description
Lab grown diamonds refers to the diamond with the same chemical composition, crystal structure and physical characteristics produced by certain technology and process flow in the laboratory or factory; It's polished gem-grade diamonds; Also known as technology diamond, synthetic diamond.
Cultured diamonds, also known as "synthetic diamonds", are artificially grown diamonds in a laboratory. At present, there are usually two ways to grow diamonds: HPHT (high temperature and pressure) and CVD (chemical vapor precipitation). Cultured diamonds have similar chemical composition, physical properties and crystal structure to natural diamonds, making it difficult to distinguish them with the naked eye.
Due to the different natural environment, the molecular structure of artificial diamond is not the complete octahedral structure of natural diamond but a complex structure, which will produce phosphorescence phenomenon. With the maturity of artificial diamond production technology, its low cost, and can produce a variety of colors of diamonds and in the jewelry market. While synthetic diamonds from laboratories and factories have been around for decades, synthetic diamonds of gem-quality have only recently emerged. Synthetic diamonds were originally used for industrial purposes such as making cutting tools, but they are also used in jewelry.

Lab grown diamonds are exactly the same as natural diamonds, no different.
Advantages Of Lab Grown Diamonds
Diamond has prominent advantages in cost performance, and its industry acceptance and standardization are increasingly strengthened.
High temperature and high pressure diamond technology is also developing. HPHT used to focus only on small gem-grade diamonds, but in recent years, many HPHT diamond manufacturing companies have also begun to produce large carats, some even more than 10 carats. HPHT diamonds can now be internally purified to VVS grade. The biggest advantage over CVD diamonds is the high level of colour.
But HPHT's adamantine luster is no better than CVD diamonds, and adamantine is usually the result of a very high refractive index and good cutting -- it's one of the sharkiest shiny transparent stones in the gemstone world. Diamonds Diamonds are undoubtedly the shiniest of all diamonds. The diamond-like sheen of CVD diamonds is almost as good as that of natural diamonds, while HPHT is not as good. So most of the jewelry industry will use HPHT diamond as cherry stone, because it is very good color, like a little cherry stone shiny, very perfect.
