|---|---|---|
name |
string | Name of the stone or jewel, as sold or as later known. |
stone |
string | Description: color grade, cut, clarity, origin or setting, as catalogued. |

price_usd_millions |
numeric | Price in millions of US dollars as the chapter’s table gives it, including the buyer’s premium. |

price_usd_basis |
string | exact_usd_total when price_usd is an exact figure published in US dollars; usd_millions_rounded when it comes from the rounded table figure. |
local_price |
string | Price as the house announced it, in the currency of the sale. |
local_currency |
string | ISO 4217 code of local_price: USD, CHF or HKD. |

stated_record |

notes |

sources |
string | Sources in Chapter 14’s list that name this sale: lot records, press releases and GIA reports, separated by " | ". |

Sources and how they were checked
The table was rebuilt in September 2026 from auction house primary records: Christie’s lot pages and sale results, Sotheby’s press releases and catalogues, and GIA Gems & Gemology auction reports. Every price is the figure the selling house published, which includes the buyer’s premium. No row rests on Wikipedia.
usd_per_carat is Erebaur’s arithmetic: price_usd divided by carats. Where the house published an exact US$ total, that total is used. Otherwise the table’s US$ figure is used, which is rounded to US$0.1 million, and price_usd_basis says which of the two applies.

Known limitations
- A selection of notable record sales, not every sale above a threshold. Spirit of the Rose is left out because no lot record could be retrieved, and the Marie Antoinette pearl pendant, the natural pearl record, because no carat weight could be.
- Auction results only. Most gems change hands in confidential dealer transactions, so a stone sold privately for more does not appear.
- Prices include the buyer’s premium; pre-sale estimates do not, so a price and an estimate are not on the same basis.
- US$ figures for sales announced in Swiss francs or Hong Kong dollars come from the house or from GIA at the exchange rate on the day of sale, so US$ prices from different years are not directly comparable.
- Ranking first in a category here is not a record claim.
stated_recordcarries the claims Chapter 14 makes; The Rock, for example, tops the colorless rows but the chapter makes no record claim for it. - Chapters 13 and 15 mention further prices in their text, but neither holds a structured auction price table, so nothing from them is included.
