Auction-realized prices and the luxury-equity backdrop

What the quarter told us

  • The year's flagship quarter: Q2 2025 cleared $202.3M across 13,308 sold lots, up 37% in gross value and 68% on a like-for-like basis, the Geneva Magnificent Jewels sales driving the strongest jewelry quarter of the year.
  • The Geneva May and June sales were the quarter. May ($78.7M) and June ($104.8M) together carried roughly 91% of the value, against a quiet April.
  • Historic colored stones and colored diamonds led the top. A Marie-Thérèse Pink colored diamond realized $13.98M at Christie's, ahead of the $11.3M Blue Belle sapphire necklace and the $9.5M Regent Kashmir sapphire ring.
  • Christie's dominated, clearing $103.0M (about 51% of the quarter) across 455 lots, with Sotheby's ($56.9M) bringing the two flagship houses to roughly 79% of value.
  • Diamonds anchored the market at $94.9M, but colored stones carried the headlines: sapphires added $45.4M, rubies $22.6M and emeralds $14.1M, the colored-stone share unusually high.
  • The high end traded apart from the equities. The broader luxury majors de-rated in the spring (LVMH about −22%), yet the auction jewelry market rose and Richemont's jewellery maisons, Cartier and Van Cleef & Arpels, remained the sector's most resilient division.

Three trends that will define the year

“The high-jewelry market stayed firm while the broader luxury complex de-rated: in Geneva, historic colored stones and fancy-colored diamonds drew the deepest bids of the year.”
