Diamond Dave Sackadorf — a 1986 and 1988 graduate of the Gemological Institute of America — has built a distinguished career defined by expertise, integrity, and a lifelong passion for fine jewelry. Known throughout the industry for his honest and reliable service, Dave has earned a reputation as a true professional, offering an exceptional selection of one-of-a-kind pieces, fine pre-owned watches, antique jewelry, and signed designer treasures.
In 1998, Dave founded Vienna Jewelry & Estate Buyers in Vienna, Virginia — an upscale suburb of Washington, D.C. Leveraging his extensive network of collectors, auction houses, antique dealers, and jewelry associations, Vienna Jewelry quickly became one of Washington’s leading jewelry buyers.
After more than two decades of success, Dave sold Vienna Jewelry in 2020 and established Loudoun Jewelry, allowing him to continue serving clients closer to home in the community he’s called home for over 30 years. By December 2023, Dave decided it was time to slow the pace and return to the heart of what he loves most — working one-on-one with clients as a private jeweler.
Today, Diamond Dave continues to share his passion and expertise through personalized service in engagement rings, custom designs, repairs, appraisals, and estate jewelry — offering every client the knowledge, care, and craftsmanship that have defined his career for nearly four decades.
