About This Dataset
Most Expensive Diamonds and Gemstones Sold at Auction (All Time)
Precious stones ranked by hammer price at public auction in millions of USD. Blue and pink diamonds consistently command the world's highest prices per carat at auction, driven by extraordinary scarcity — gem-quality blue diamonds represent less than 0.001% of all mined diamonds, making each major specimen a genuinely unique object that major auction houses treat as a once-in-a-generation event.
Analysis
CTF Pink Star Diamond heads the table on 71.2, ahead of Oppenheimer Blue Diamond (57.5) and Pink Legacy Diamond (50) in Auction Price (Million USD) in 2022. 47.4 separates the highest figure (71.2) from the lowest (23.8). First and second are separated by 13.7, so the leader sits inside the field rather than apart from it. Places 3 to 8 are close together, spanning 50 to 23.8.

How the figures are calculated
- Values use the measure and unit named on this page. Consult the dataset description and cited source for coverage, definitions and any unit conversions. Displayed values may be rounded for readability.
- Missing years are left empty rather than estimated — no interpolation, no carrying a previous year forward.
- Change is measured between the first and last year in which an entity actually reported a value, so a series that starts late is not penalised for the years before it existed.
- The compound annual rate is (last ÷ first)^(1 ÷ years) − 1, using those same two reported years.
- Entities are ranked highest-first on their value in 2022.
- An entity that reported nothing in the latest year is still listed — it follows the ranked entities in the table rather than being dropped.
