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.
