Smyrna, GA

Cumberland Diamond Exchange (CDE) is an award-winning, family-owned jewelry store proudly serving Cobb County and the greater Atlanta community since 1982. Located in Smyrna, less than a mile from Truist Park, we specialize in loose diamonds, engagement rings, wedding bands, custom designs, pearls, colored gemstones, estate and vintage jewelry, watches, repairs, and appraisals. Built on relationships, philanthropy, and excellence in customer service, we’re more than just a jewelry store—we’re a part of the community. For over four decades, generations of families have trusted CDE to celebrate life’s most meaningful milestones, while we continue giving back by supporting more than 40 nonprofits—including The WellStar Foundation, SafePath Children’s Advocacy Center, LiveSafe Resources, Shepherd’s Men, and the Cobb Community Foundation—and staying active in professional organizations such as the GIA Alumni Association, the National Association of Jewelry Appraisers, and the Smyrna Business Association.
