The Mozambique Diamond GRA Certificate is a specialized certificate that certifies the condition, texture, and weight of Mozambique diamonds. However, the GRA certificate clearly imitates the GIA certificate and is recognized as a counterfeit certificate without authority. So if your seller tells you that they can issue a Mosang Diamond GRA certificate, then be careful.
Difference between GRA certificate and GIA certificate
1. GIA is a non-profit organization funded by donations from professionals in the jewelry industry.
2. GIA's main service scope is education and research in jewelry appraisal and professional knowledge, which is highly recognized by the global jewelry industry; GRA studies moissanite, which is a type of jewelry in nature with a hardness second to diamond but a price only one tenth that of diamond.
3. GIA was founded by Robert M. Shipley in 1931, and was the pioneer in promoting diamond certification as international; GRA is currently an institution with nowhere to verify its authority.
