What is the difference between CVD and HPHT Lab Grown Diamonds?
Lab-Grown Diamonds are created via two methods – Chemical Vapor Deposition (CVD) and High Pressure High Temperature (HPHT). What is the difference between CVD and HPHT Lab Grown Diamonds? While HPHT diamonds are more closely connected to the typical growth patterns of mined diamonds, CVD growing is known to produce finer stones, as it is a newer growth method. What are CVD Diamonds? CVD stands for Chemical Vapor Deposition – a process where machines use a vacuum method to compile atoms and form solid materials. Researchers discovered they could use this process, which was popular in the semiconductor industry, to...
These Diamonds have the same GIA grade. How come?
On websites like “BlueNile” or “RareCarat”, the diamond on the right would be advertised as “the same diamond at a bigger discount”. Within the diamond industry, however, the diamond on the right is advertised as “rejection” or “bluff” goods.
