At Doumato Jewelers, every diamond and gemstone passes through the hands of a trained expert. Amanda Doumato and Cheryl Gallagher hold the Graduate Jeweler diploma from the Gemological Institute of America (GIA), the jewelry industry's standard credential for gemological expertise. The GIA program covers both diamonds and colored stones and pairs in-depth study with hands-on lab training: grading diamonds with the 4Cs, identifying gemstones, and recognizing treatments and imitations using professional instruments. For you, that means the jewelry you choose at Doumato Jewelers has been evaluated with the same rigor and precision the industry relies on, so you can buy with confidence and wear it with pride.
