Certification · GIA & IGI
Certified diamonds,
from a lab buyers trust.
Natural diamonds come with GIA certificates; lab-grown diamonds come with IGI certificates. Both grade each stone against the 4Cs — carat, cut, color, and clarity — so it can be verified independently. Certificates are available on request and ship with the goods. Lab-grown diamonds are inherently conflict-free.
The Documentation
What backs every stone.
Natural — GIA
Natural diamonds come with GIA certificates. The Gemological Institute of America grades each stone against the 4Cs and issues the report buyers and their customers recognize. Certificates are available on request, supplied with the goods.
Lab-Grown — IGI
Lab-grown diamonds come with IGI certificates. The International Gemological Institute grades them against the same 4Cs as a mined stone. Lab-grown diamonds are inherently conflict-free — created in a controlled environment, not mined.
The 4Cs
Every certified diamond is graded on carat weight, cut, color, and clarity. The certificate records those grades in writing, so the stone can be verified independently of us — by you, and by the customer standing at your case.

The Specifics
Certification, answered straight.
Yes. Natural diamonds come with GIA certificates; lab-grown diamonds come with IGI certificates. Certificates are available on request — ask for them with your quote or before you place the order, and we issue them with the goods.
Both grade a stone against the 4Cs — carat, cut, color, and clarity. We pair natural diamonds with GIA reports and lab-grown diamonds with IGI reports, matching each stone type to the lab buyers expect to see on that category.
Lab-grown diamonds are inherently conflict-free — they are created in a controlled environment rather than mined. Each is graded by IGI and reported against the same 4Cs as a natural stone.
Yes. Every certified diamond, natural or lab-grown, is graded on the 4Cs: carat weight, cut, color, and clarity. The certificate records those grades so you and your customer can verify the stone independently.
Certificates are available on request. Tell us when you request pricing or place the order, and the GIA (natural) or IGI (lab-grown) report is supplied with the diamond.
