AvantGold Jewelers has launched a Web site (www.avantgold.com) featuring upscale designer jewelry and the store's services, including custom designs, watch repairs, and insurance replacement appraisals. Plans call for adding an online newsletter and other educational features. Photographs of high-end jewelry, a virtual-reality tour of the store, and a flash-enabled designer section characterize the site. There are profiles on the staff, including a humorous page where the store's canine mascots, two Irish Wolfhounds and a Chow, share their hobbies, biggest secrets, and most embarrassing moments. AvantGold does not currently sell anything online, but the site has a survey asking visitors if they would consider buying jewelry online.
