Lab Grown Diamonds Description
There are now two main methods of lab grown diamond production: the high pressure/high temperature process (HPHT) and the chemical vapor deposition process (CVD), both of which are commonly used. CVD is suitable for producing cultivated rough diamonds of more than 3.5 carats due to the limitations of process and production cost. The rough diamonds of this weight will be more than 1 carat bare diamonds after grinding and cutting. Increasingly popular for the production of gem-grade synthetic diamonds used in jewelry. HPHT rules of high temperature and high pressure cultivation of all sizes of diamonds are suitable for growth, the current limitation is that the growth chamber of the press is generally small, a single press output is extremely limited.
Characteristics Of Lab Grown Diamonds
HPHT and CVD diamonds have the same optical, physical, and chemical properties as natural diamonds, and they have exactly the same hardness of 10. At present, most lab grown diamonds are naked, and the naked eye can no longer distinguish between natural diamonds and lab grown diamonds. However, these lab grown diamonds do leave some grain signs of growth as they grow, which can be identified by an authoritative diamond appraisal agency with a specific instrument.
If the lab grown diamond is in the rough state, this is very easy to distinguish, once the lab grown diamond is processed as a naked diamond, only with the naked eye is unable to distinguish the lab grown diamond and natural diamond.
HPHT diamonds, on the other hand, form a cubic octahedral shape with 14 growth directions. CVD diamonds form a cube shape with one direction of growth.

From a scientific point of view, cultivated diamonds are exactly the same as natural diamonds, the only difference being where they are formed.
Prospects And Advantages Of Lab Grown Diamonds
lab-grown real diamonds like natural diamonds! Before that, who would have thought it possible to use technology to produce diamonds? Growing diamonds is a combination of technology and romance, and it is very affordable, it is the best choice for budget consumers.
