Our team examines every diamond before we purchase—we inspect every diamond against its certificate to confirm its quality.
The majority of DeRocks diamonds are certified by the Gemological Institute of America (GIA)—the world’s leading authority on diamonds. We also sell diamonds with other certificates when they meet our high quality standards.
Your GIA-certified diamond
Every diamond that’s issued a Gemological Institute of America (GIA) Diamond Dossier has the report number inscribed on the diamond’s girdle. This is an added layer of security to make sure you get the exact diamond you selected. A copy of your uniquely numbered GIA certificate is also kept permanently on file with GIA and can be replaced any time if lost or destroyed.
Committed to conflict-free diamonds
We know every step in a diamond’s journey from mine to market. All our diamonds comply with the strict Kimberley Process Certification requirements to certify that they’re conflict-free.
We’re a member of the World Federation of Diamond Bourses and the Diamond Exchange of Singapore. When you choose DeRocks, you can be sure that you’re choosing an ethical diamond.
If you have any concerns about the quality of your diamond, contact us within 60 days of purchase and we’ll happily arrange for an independent appraisal.
