Q1 2026 Report: The Secondary Market for Fine Jewelry & Gems
Auction-realized prices and the luxury-equity backdrop
A between-flagships quarter that firmed where it counts: with no Geneva marquee sale, the regional and London books carried the period, and value at the houses tracked in both years rose sharply even as the listed luxury majors sold off.

The read
What the data shows
For a buyer the quarter rewards attention to composition rather than headline totals. With the flagship Geneva calendar quiet, London did the heavy lifting: Christie's led on value across a tight run of important lots, headed by a half-million-dollar diamond ring. Diamonds set the ceiling while emerald, jade and sapphire carried the colored-stone interest, and the top lot firmed some sixty percent over the prior year, a sign that quality of consignment, not volume, is what held price.
