Selection of rings from Koller's jewllery auction

HISTORICAL JEWELLERY
WITH A NOBLE PROVENANCE

PREVIEW: JEWELLERY, 26 NOVEMBER 2025

The highlight of the large selection of Cartier items is a solitaire ring from the Art Deco period, set with a large diamond weighing over 10 carats. From the brand's vintage era, which is currently in high demand, we are offering a previously little-documented zebra bracelet. Alongside the zebra is a scarab brooch in the Egyptian Revival style.

CARTIER
HIGHLIGHTS

The November sale also contains icons of the 20th century: an emerald and diamond bangle by Van Cleef & Arpels, and a pair of earrings from Bulgari's iconic ‘Monete’ collection. Other highlights include a diamond ring weighing over 10 carats, and Colombian emerald ear clips of 10 and 8.8 carats.

A tiara set with diamonds, created around 1900, and a dazzling Art Deco bracelet with Ceylon sapphires from the House of Borbón y Braganza have royal origins. A fleur-de-lis brooch, adorned with Burmese rubies and diamonds, bears the heraldic emblem of this Spanish–Portuguese noble dynasty – jewellery in which history and beauty are inseparably intertwined.
