Top 50 Diamonds by Quality

Our quality score measures pure gemological quality. Cut, polish, symmetry, and proportions. These are the best-made stones in the market right now.

How to Read the Quality Leaderboard

The quality score is a 0-100 index that weights the things that make a diamond actually look good: cut grade first, then polish and symmetry, then proportions (table %, depth %, length-to-width ratio). It deliberately ignores color and clarity, because those grades affect paper value more than appearance, and we want this list to surface diamonds that will look exceptional in person.

Use this list when you care more about sparkle and fire than paper grades. A 1.2ct H/SI1 at 98 quality will out-perform a 1.2ct D/FL at 85 quality in every real-world lighting condition. The light return, the brilliance, the way the facets are aligned. If your priority is 'the stone that looks the most alive when she glances down at her hand,' start here.

These rankings refresh every 24 hours as new stones are added and old ones sell out. A stone in the top 10 today may be gone tomorrow. Click any entry to see full specs, multiple retailer prices (where the same certificate number is listed across our network), and side-by-side comparisons.
