In 1983, English natives Denis and Karen Boulle launched de Boulle Diamond & Jewelry in Dallas, in a small salon. The couple introduced the city to many luxury-watch brands, along with fine jewelry collections and then moved to its much larger current location in 2001. The building had been a toy store, a restaurant and a bank, but after much reconstruction, it was transformed into a sophisticated 13,600-square-foot, two-story, French-style villa. In 2019, Denis and Karen thought it was time to renovate their flagship store, from lighting to walls, floors and showcases, without changing the interior architecture.
