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.

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.

Colombian emerald earrings (4.70 and 3.46 carats) brought in €365,400 ($428,229), far exceeding the €60,000 estimate.

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.
