A new survey, analyzing state-by-state data from approximately 15,000 trade-ins by WP Diamonds, reveals some fascinating tidbits about diamond trends across the US.
For instance, the survey shows that people in Maryland, Michigan, and Illinois own the biggest diamonds, while New Yorkers, Floridians and Californians own the best quality diamonds (highest average value per carat). California, Florida, and North Dakota lead the US at highest average secondhand jewelry values.
The most popular diamond shape in the US is the round diamond, accounting for approximately 55% of trade-ins. The second most popular shape is the Princess cut (22%), followed by marquise (4.8%) and emerald (4.7%).
Here are some more revealing numbers from the survey:
• Maryland leads all 50 states in terms of largest diamonds owned, with an average weight of 1.75 carats per stone. Vermont is at the bottom of that list, with an average weight of 1.03-carats per stone.
• California leads the way at highest average secondhand jewelry values. Nevada ranks last on that list.
• While round is the most popular shape all across the country, Minnesota seems to rank it higher than the national average: more than 73% preferred the round shape. In Texas, the average is lower than the national average – 39%.
