Records set in 2025 and 2026
The 2026 ceremony set the new top value. Other 2026 pieces had stated carat weights but no stated dollar values, such as Rose Byrne’s 22.58-carat smoky diamond and Teyana Taylor’s Tiffany necklace with an internally flawless emerald-cut diamond of over 18 carats.
What drives these prices
- One big stone. The top values come from a single rare diamond.
- Loans. Jewelers lend pieces for exposure, so the value is publicity, not spend.
- Colour rarity. Green, blue and yellow diamonds carry large premiums.
- Estimate drift. Press values rise with each retelling, which we flag.
