Q1 2025 Report: The Secondary Market for Fine Jewelry & Gems
Auction-realized prices and the luxury-equity backdrop
A quiet quarter between the Geneva flagships: the regional and London books carried the period, diamonds anchored the value, and the market held its level like-for-like as the listed luxury majors split between a January rally and a spring de-rating.

The read
What the data shows
With the Geneva calendar dark, the regional and London rooms did the work. March alone cleared roughly $14.1 million, about seventy percent of the $20.0 million quarter, and read like-for-like across the houses present in both years, value actually firmed about eight percent. Christie's and Bonhams led, topped by a $324,324 diamond ring in London. Diamonds anchored the period at some $10.2 million, with sapphires, pearls and rubies carrying the colored-stone interest below. A base effect, not a market drop.
