JON PARKE, G.G.,JK Jewelers, St. George, Utah What new jewelry did you invest in last year? Two watch lines—Swiss Star and Fossil—because I never carried watches before. How's it selling? They're working out as well as I thought they would. They have low margins … but they're hot and they sell like crazy. JOHN MICHAELS, Michaels Jewelers [regional chain], Waterbury, Conn. What new jewelry did you invest in last year? We expanded our Hearts On Fire diamond selections, our multicolor or rainbow sapphires, and our enhanced or irradiated blue diamonds—we're calling them "blue ice." How's it selling? We bought in September, and sold three-quarters of the merchandise by Christmas. KARIM MOHAMMAD, Robinson Jewelers, Arlington, Texas What new jewelry did you invest in last year? Pearls, 18k white gold, and designer titanium bands, since we're going after the bridal market.
