Asprey demonstrates how stones can work together to create a piece that is truly exceptional. The center stone of this ring is a beautiful blue 22.47 carat cabochon chalcedony. It is enhanced by a ring of lively diamonds and an exposed shank of 8.97 carats of deeply saturated blue sapphires. Set in 18k gold. This ring is size 7 and can be resized up or down one size. In 1937, the Duke of Windsor commissioned famed jeweler Suzanne Belperron to design a stunning suite of blue chalcedony, blue sapphires, and diamonds for his Duchess, Wallace Simpson. The suite is exceptional in that it is made primarily of blue chalcedony, the very hue of the stone in this ring, with only small accents of blue sapphires and diamonds.
