DALLAS — This past October, Richard D. Eiseman Jewels here became the first U.S. retailer to carry the fine jewelry of London designer Elizabeth Gage in an in-store boutique. Until now, Gage has sold her work in the U.S. only through private showings typically held at hotels. Her own shop on Abermarle Street in London has been open since 1984. “She does a wonderful business in the States,” commented Richard Eiseman Jr., who owns and operates the store. “Her jewelry is so wearable and translates easily from day to night. We’re having a couple of functions to welcome her, and the phone calls from our clients have been ecstatic.” Eiseman was selected as the first jeweler to stock the collection because it offers the same kind of personal attention as Gage does in her London store. “We feel Texas as a whole is a good market for us,” Simpson added. Gage will continue to stage private showings of her collection once annually in New York and Los Angeles. After seeing how the retail relationship with Eiseman works, the company will probably sell to additional U.S. stores, Simpson added. A full range of Gage’s earrings, necklaces and rings will be prominently displayed at the front of the Eiseman store in NorthPark Center here. “Because the majority of the jewels are comfortably priced between $2,000 and $10,000, we anticipate a strong response,” he added. Simpson said she expects Eiseman will sell more than $500,000 a year of Gage’s pieces, but Eiseman declined to comment on sales projections. Gage, an English blue blood, designs classic one-of-a-kind pieces that mix 18-karat gold with pearls, precious stones, ancient coins and antique amulets. About 25 percent of her business is in commissioned pieces. Other designer collections at Eiseman, established in 1965, include Henry Dunay, Michael Bondanza and Faberge.
