A cushion brilliant-cut, 9.67-carat fancy vivid orangey-yellow diamond ring also caused a stir, selling for €2.1 million ($2.5 million), six times its upper estimate.
Other highlights included:
Chaumet Pearl Necklace: Comprising 191 natural pearls and a diamond clasp, this classic piece sold for €1.6 million ($1.8 million), outpacing its €600,000 valuation.
Kashmir Sapphire Ring: Featuring a 7.76-carat antique cushion brilliant stone, the ring achieved €869,400 ($1 million), more than double its estimate.
Natural Pearl Necklace: A strand of 41 natural pearls drew €504,000 ($590,661)—a staggering 16x its €30,000 high estimate.
Several Boucheron pieces also performed notably:
A pair of fancy intense yellow diamond earrings realised €441,000 ($516,828), landing within the expected range.
Colombian emerald earrings (4.70 and 3.46 carats) brought in €365,400 ($428,229), far exceeding the €60,000 estimate.
A 7.30-carat emerald ring with triangular diamonds matched that price, also outstripping its pre-sale valuation.
A matching ruby and diamond necklace-earring set, featuring over 50 carats of Burmese rubies, sold for €327,600 ($383,929).
A 13.47-carat Ceylon sapphire ring, mounted with baguette diamonds, closed at €327,600 ($383,929), more than tripling its high estimate.
The auction presented a mix of heritage artistry and gemstone rarity from maisons such as Cartier, Boucheron, and Chaumet—showcasing continued global demand for investment-grade jewels.
