Are HPHT Diamonds Certified by a Recognized Gemological Laboratory?

Yes, they are. All of our diamonds are accompanied by a diamond grading report issue by a reputable, internationally renowned gemological laboratory.

HPHT diamonds are required to be sent to a recognized gemological laboratory before a label of certification will be awarded. Most of our diamonds are submitted to the Gemological Institute of America (GIA) and are carefully screened for any hint of artificial substances. There is full disclosure of the nature of the treatment and each diamond is accompanied by a internationally recognized diamond grading report.

Occasionally, we also submit our diamonds to another international gemological laboratory of repute.
