HPHT Diamonds

High Pressure and High Temperature (HPHT) Diamonds


HPHT, which stands for 'High Pressure and High Temperature,' is a process used in creating CVD diamonds. This method replicates the natural diamond formation that occurs deep underground. Over recent years, HPHT technology has advanced significantly, making HPHT CVD diamonds increasingly popular for their stunning beauty and affordability.
