The country’s most innovative retailers share their secrets for a sparkling holiday season and a brilliant new year

Every month we scour the country searching for jewelers to feature as Innovative Retailers: store owners who are at the top of their game in sales, merchandising, customer service, marketing, technology developments, and more.

This issue, we hit the jeweler jackpot. Here, we profile five who in some ways couldn’t be more different: a 3-D printer–loving manufacturer; a third-generation luxury two-store proprietor; a 121-year-old multi-brand family business; a high-end boutique owner/private-label designer; and a $100 million–per–year diamond ­merchant. What they all have in common: They’re on retail’s cutting edge. And from what we’ve seen, that’s a pretty exciting place to be.
