Manhattan jeweler Stephen Russell (212.570.6900, www.stephenrussell.com), known for its exceptional period pieces, has moved a few doors down Madison Avenue into a boutique at the corner of 76th Street. The new venue, which includes a private salon on the lower level, gives company owners Stephen Feuerman and Russell Zelenetz more than twice the space they previously had to present their new pieces and their burgeoning collection of Victorian, Edwardian, Art Deco, and retro designs. . . . Geneva-based jeweler Avakian (www.avakian.com) opened its first U.S. boutique last December at the Beverly Wilshire Four Seasons in Beverly Hills, Calif. The family-owned company, which also has stores in London, Geneva, and Moscow, creates fanciful jewelry and elaborate high-jewelry pieces adorned with emeralds, rubies, sapphires, and diamonds.
