How to Read the Overall Leaderboard
The overall score is a 0 to 100 composite of three signals we already publish individually: quality (how well the stone is made), value (price versus the peer-median for its spec), and certification (how rigorous the grading lab is). A high overall score means the stone wins on all three at once, not just one. The diamonds at the top of this list are the ones the market is putting forward today as genuinely the best available.
Use this when you do not have a strong preference yet and want to see what the market is rewarding right now. The overall list mixes natural and lab-grown freely, so do not be surprised to see them side by side. If you have a hard preference for one origin, use the Natural / Lab-grown / Fancy tabs above to filter.
Composite scores hide the trade-offs. A diamond at 92 overall might be 99 quality and 85 value, or 88 quality and 96 value. Click any entry to see the full breakdown, and use the per-metric leaderboards (quality, value, certification) when you want to optimise for one axis specifically.
