The CTF Pink Star holds the standout documented result in the available auction examples: GIA reported that the 59.60-carat Fancy Vivid pink diamond sold for $71.2 million at Sotheby’s Hong Kong in 2017. That is a price achieved for one specific diamond at one sale—not a current retail valuation or a guide to what another pink diamond is worth.
A fully comparable ranking of 25 jewels and gemstones cannot be established from these records. The examples below show notable auction results, with dates and price definitions kept attached to the figures. Auction prices describe what a buyer paid for a particular lot under particular conditions; they do not establish the present value of other stones of the same type.
Notable high-value gemstone and jewel auction results
These examples are not a ranked top 25. They are selected records reported by gemological, auction-house, and news sources. They also do not all describe the same kind of object: some are identified diamonds, while the Sunrise Ruby and Light of Africa are colored stones. Where the source does not establish whether the quoted amount includes buyer’s fees, that distinction is left unstated rather than assumed.
| Stone or jewel | Reported result | What the source establishes |
|---|---|---|
| CTF Pink Star | $71.2 million | GIA reported that the 59.60-carat Fancy Vivid pink diamond sold at Sotheby’s Hong Kong in 2017. Sotheby’s later described it as its record for a diamond and any jewel sold at auction. The figure is a sale result, not a current valuation. GIA’s 2017 report. |
| Sunrise Ruby | $30.3 million | Sotheby’s identifies this as the ruby’s auction price. Its cited page is a retrospective; it does not establish a current appraisal for this ruby or for comparable rubies. Sotheby’s ruby auction-record page. |
| 118.28-carat D-Flawless diamond | $30.06 million | GIA reported that it sold at Sotheby’s Hong Kong in 2013, describing it as the most expensive colorless diamond sold at auction at that time. GIA’s 2013 report. |
| Blue diamond | $57.5 million | GIA’s 2022 auction coverage reported this result and called the diamond the third most valuable diamond of any color sold at auction at that time. That is a dated ranking, not a claim about its position today. GIA’s 2022 coverage. |
| Mellon Blue | 20.5 million Swiss francs, or $25.6 million, including fees | The Associated Press reported the sale at Christie’s Geneva in 2025. The dollar amount is the AP-reported conversion; the source specifies that the sale total includes fees. Associated Press report. |
| Light of Africa | Just over $20 million | GIA’s 2022 auction coverage identifies the stone as a 103.49-carat diamond and reports the result as just over $20 million. GIA’s 2022 coverage. |
Why these prices do not make a reliable “top 25”
A ranked list only means something when its boundaries and price method are consistent. Auction results can mix loose stones with finished jewelry, prices before fees with totals including fees, and currencies converted on different dates. A ranking also needs a defined sale universe and cutoff date: for example, all public auctions worldwide, or only sales documented by a specific source.

- Accessories are NOT included.
- Object: A finished jewel can include design, craftsmanship, and other stones; it is not directly comparable to a single loose gemstone.
- Price definition: The hammer price and the amount reported including buyer’s fees are different figures. A source’s number should not be silently treated as one or the other.
- Currency and date: Converted prices can shift with exchange rates. A current ranking would need a common conversion date and a stated method.
- Record scope: “Most expensive” can mean the highest price for a ruby, a colored diamond, a colorless diamond, a particular auction house, or any gemstone at auction. Those are not interchangeable categories.
- Evidence: The examples here do not provide 25 consistently documented entries, so they cannot support a definitive ordered list.
What an auction record says about a gemstone’s worth
An auction result establishes what a particular lot sold for at a particular time and venue. It does not, by itself, establish a current resale price, a retail price, or the value of an ordinary stone with the same gem type. Weight, grading, color, condition, provenance, sale circumstances, and competition between bidders can all affect a result.
Provenance—the documented history or ownership of an object—can add value beyond the stone’s physical characteristics. GIA’s research on the Windsor jewels found that provenance generated bids many times their intrinsic market value. That is a reason to be cautious about treating a famous jewel’s auction price as a per-carat benchmark for an otherwise similar gem.

How to read “worth” claims responsibly
When evaluating a high-value gemstone claim, look for the sale date and venue, the identity and description of the stone, its weight and grading, whether the lot was a loose stone or finished jewel, and whether the quoted figure includes fees. A record claim should also identify its category and the date through which it applies. Without those details, a headline figure may be accurate as a historical auction result yet misleading as a statement of what the stone—or another stone—is worth now.
