At a remarkable 20.86 carats, this superb emerald-cut Alexandrite is a true rarity, weighing almost four times more than even the finest examples of this incredible stone. The Alexandrite is set in platinum and 18K gold amidst 1.73 carats of diamonds. While the Alexandrite’s almost magical trait of dramatically changing colors in varying light makes it extremely valuable, its history makes it all the more intriguing. This particular example is extremely scarce in this substantial size and represents a most fortuitous find.
