GIA Official Retailer

The Gemological Institute of America (GIA), established in 1931, is the world’s largest and most respected nonprofit institute of gemological research and learning. GIA's mission is to protect all buyers and sellers of gemstones by setting and maintaining the standards used to evaluate gemstone quality. The institute does so through research, gem identification, diamond grading services and a variety of educational programs. GIA is the creator of the revolutionary 4Cs (carat, color, clarity, and cut) of diamond, and developed its International Diamond Grading System™,  a standard used by jewelry professionals around the world to compare and.evaluate the quality of diamonds

Riginov is proud to be part of GIA's Official Retailers and have our name listed on the GIA network. GIA’s Retailer Lookup is an excellent way for the gem and jewelry buying public to ensure their trust in finding retail jewelry stores carrying diamonds graded by GIA or employing GIA-trained staff. 

“The GIA Retailer Lookup is a valuable tool - it has opened up our customer network and helped us connect with those looking for a jeweler with high standards, focus on quality and transparency. We are very excited about the potential for this tool to help us reach new customers and grow our brand.” - Riginov 


Riginov customers have convenient access to competitive wholesale diamond prices directly through our website. They can filter diamonds based on whether they are GIA certified or not, and to view the actual GIA certification. These reports come with a unique identification number that can be further verified through the GIA website so customers can be reassured that the diamond they are buying is as advertised.
