Natural Earth-mined diamonds that have gone through High Pressure High Temperature (HPHT) process permanently changing the color of the stone from slightly colored to white. HPHT process does not change the clarity of the stone.
The HPHT process can only be done on rare Type Ila diamonds. Type Ila diamonds make up only about 2% of the world’s diamonds. The HPHT process puts the diamond into a controlled environment mimicking the natural process in which diamonds are created. In this high temperature (1800 to 2400 degrees Fahrenheit) and high pressure environment, the diamonds are allowed to continue the natural process so they may reach their full color potential.
HPHT natural diamonds should be differentiated from Lab Grown diamonds and Clarity Enhanced diamonds.
All our HPHT diamonds (1ct plus) are submitted to GIA for grading. The HPHT process is a permanent process making all HPHT diamonds valid candidates for GIA grading. GIA stringent laboratories can accurately screen diamonds for synthetics and treatments, as well as, inscribing for accurate identification and representation.
