Markham Teguns is a third general jeweler who fills his Frisco store (which looks like a castle) with his own right-hand diamond rings, pavée bangles, and hoop earrings, as well as impeccable creations of Italian designers Roberto Coin, Marcous Bicego, and Bulgari. Shoppers can also renovate existing jewelry or have new pieces designed from scratch. Timepiece lines include Hublot, TAGag Heuer, IWC, and Cartier.
