Luxury market in review, the rise of ‘Hard Assets’
The 2025 auction season has been defined by a decisive move toward "historical importance" and "investment-grade" assets. While the broader retail market navigated economic shifts, the specialized auction rooms of Sotheby’s, Christie’s, and Phillips and others saw unprecedented competition for items with singular provenance and technical rarity.
In 2025, luxury auctions shifted from being a marketplace for "status symbols" to a high-stakes arena for "hard-asset" wealth preservation.
1. Fine Jewelry: The Diamond Standard
The jewelry auction market reached a projected valuation of $3.55 billion in 2025, driven by a 11% CAGR. The year was dominated by "Fancy Vivid" stones and historic estates.
The Mellon Blue Legacy: Highlighting the year, the "Mellon Blue"—a 9.51-carat Fancy Vivid Blue Diamond from the estate of Bunny Mellon—realized $25.6 million at Christie’s Geneva. This established a staggering benchmark for price-per-carat in the blue diamond category.
Exceptional Color: A 6.24-carat deep-blue diamond ring by Boucheron also set a record, fetching $12.7 million, confirming that high-clarity colored diamonds are currently the most sought-after asset in the jewelry sector.
Digital Transformation: Online bidding reached a new peak, accounting for 81% of total auction participation, with individual digital lots now regularly exceeding the $5 million mark.
2. Horology: Breaking the "Patek" Ceiling
2025 was a landmark year for watches, with Phillips alone achieving a $113.8 million spring season and a nearly unheard-of 99% sell-through rate.
The New World Record: In November 2025, a stainless steel Patek Philippe Ref. 1518 sold for $17.6 million (CHF 14.19M) at Phillips Geneva, becoming the most expensive vintage Patek Philippe wristwatch ever sold at auction.
The Audemars Piguet Surge: Sotheby’s New York saw a historic result for the Audemars Piguet "Grosse Pièce" pocket watch, which realized $7.7 million, shattering the record for the most expensive AP ever sold.
Celebrity Provenance: Francis Ford Coppola’s personal F.P. Journe FFC prototype realized $10.75 million, reinforcing the market’s pivot toward independent watchmakers with significant cultural ties.
3. Luxury Handbags: The $10 Million Milestone
2025 was the year the "handbag as an asset class" became undeniable. The auction market for rare maroquinerie saw its highest ceiling to date.
The Ultimate Record: In July 2025, Jane Birkin’s original Hermès Birkin bag (the 1984 prototype) sold at Sotheby’s for a record-breaking $10.1 million, becoming the most expensive handbag in history.
The Birkin Voyageur: Further proving the power of provenance, Birkin's second personal bag, the "Le Birkin Voyageur," sold for $2.9 million in Abu Dhabi.
Exotic Market Stability: Standard "investment-grade" bags like the Himalaya Birkin 30 maintained their status, with pristine models commanding roughly 2.4 times their original boutique price, offering a level of liquidity that outperformed many traditional equity indices.
2025 Auction Market High Performers
Jane Birkin’s Original 1984 Prototype Birkin: Sold for $10.1 million, setting the all-time world record for any handbag and cementing the category's status as a top-tier investment asset.

Audemars Piguet "Grosse Pièce" Pocket Watch: Achieved $7.7 million, shattering the previous record for the most expensive Audemars Piguet ever sold at auction.
