GIA Official Retailer

The Gemological Institute of America (GIA), established in 1931, is the world’s oldest, largest and most respected nonprofit institute of gemological research and learning. Unlike some other labs, GIA is not owned by wholesalers or retailers, and does not sell gemstones. 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 and developed its International Diamond Grading System™,  a standard used by jewelry professionals around the world to compare and evaluate the quality of diamonds. Diamonds that are accompanied by GIA Diamond Grading Reports are the most highly valued and trustworthy in the diamond industry.​ The GIA Diamond Grading Report is your assurance for a confident purchase.​

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

“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
