The auction will feature pieces ranging from antique and Art Deco to midcentury and contemporary designs.

According to Allison Osborn, Bonhams’ L.A. head of sale, the auction is composed primarily of private consignments, presenting collectors with a rare chance to acquire unique and storied pieces. Among the highlights are fancy-grade coloured diamonds and gemstones, including rubies, emeralds, and sapphires.

The nearly 300-lot sale includes pieces from prestigious jewellers such as Bulgari, Cartier, Chopard, Graff, and Harry Winston. One of the most anticipated items is a 12.62-carat brown-yellow octagonal diamond ring, estimated at $50,000–$80,000. Set in platinum and flanked by trapezoidal-cut diamonds, the VS2-clarity stone stands as a remarkable example of natural colour and craftsmanship.

Collectors and enthusiasts can look forward to a diverse selection of high-value pieces at the upcoming auction, which promises to be a highlight in the world of fine jewellery sales.
