According to the latest trend report from the Natural Diamond Council (NDC), the average price of an engagement ring in the United States rose 9% year-over-year to $7,364 in 2025. Round-cut diamonds remain dominant, accounting for 62% of sales, but consumers are showing a clear preference for larger carat weights—sales of 1.5 to 1.59 carat diamonds increased by 15%, and those over 2 carats grew by 10%, while sales of the standard 1-carat size declined by 7%. The report is based on data from over 4 million transactions across 2,500 jewelry retailers nationwide.
Beyond engagement rings, tennis bracelets, wedding bands, and pendants saw the strongest sales growth, with the average price of tennis bracelets reaching $3,600, up 15%. Notably, Gen Z is expected to become the fastest-growing consumer segment in 2026, with over 40% of purchases in this group being self-purchased. Additionally, influenced by male celebrities such as Timothée Chalamet and their red-carpet looks, men’s diamond jewelry is expected to continue gaining momentum.
