    Diamond Certification

    Gemesis Diamond Company’s lab-created diamonds are certified by an independent third-party institute.  Each polished diamond over one-quarter carat in weight comes with a diamond grading certificate. The certificate is available for viewing via each individual Advanced Detail page.

    Gemesis is committed to maintain supply chain integrity and providing knowledge of origin of its products. For origin certification and to distinguish its diamonds from those mined in nature, Gemesis insists that each of its lab-created polished diamonds over one-quarter carat in weight are laser inscribed with an identity name and number as part of the certification process. In addition, all promotional literature clearly and unequivocally identifies Gemesis cultured diamonds as laboratory-created.
