The certificate

A diamond certificate lists all the specific characteristics of a diamond. The certificates we work with are issued by the Gemmological Institute of America (GIA), of International Gemological Institute (IGI) or by the Diamond High Council (HRD). These are all the leading institutions in the diamond world. The GIA sets the standard for the assessment and identification of gemstones, their assessment system serves as an international benchmark in the jewelery and gemstone industry. So make sure you get a diamond certificate. With us, a certificate is always included with your purchase at 0.30 ct or higher. Below 0.30 ct. You can choose whether you want a certificate.
