the sparkle rundown

WP Diamonds, the nation’s leading online buyer and partner for retailer buy-back of diamonds , jewelry and watches, is excited to announce the launch of America’s Diamond and Jewelry Ranking. The company’s last 15,000 consumer inquiries and data have informed these findings, covering all 50 states.

America’s Diamond and Jewelry Ranking is the first report of its kind that directly analyzes ownership across the United States.

Although plenty of reports have been issued by authorities regarding the mine-to-market process, rough diamonds, bridal and retail sales statistics, this is the first report that analyzes data based on what consumers already own. State-by-state, a feel for diamond and jewelry preferences and taste can be deduced, with surprising results.

Answering an important question for the diamond-curious and jewelry enthusiasts across America…where does your state rank?
