Potomac jeweler George Kaufmann, formerly with the now-closed Robert Bernard Jewelers at Potomac Woods Plaza, opened a new store at Park Potomac last week with son Corey as his partner. Kaufmann has been in the jewelry business for most of his life, learning the trade from his own father at a Kaufmann store in D.C. that dated back to the 1940s. The new Kaufmann Jewelers, 12500 Park Potomac Avenue across from Sugo and MoCo’s Founding Farmers, will offer repair service and custom work on gold, diamonds, gemstones and watches.
