Tiara Galleries & Gifts, a fixture at Congressional Plaza for the past two decades, is making big changes for 2015. Next month the store will get a new name (Silver Moon Jewelry & Accessories), a new location (the former Harry & David space a few doors down), and a new focus on jewelry and handbags. “We won’t be carrying any more crystal or porcelain,” says owner Irv Losman. “Those ‘older’ categories were my dominion — but the rest of my staff is more in tune with lines like Brighton, Spartina, Vera Bradley, Endless, Pandora, and Alex and Ani. We’ve decided to do a smaller, more streamlined store that appeals to women in a different way.”
