An exquisite William & Son diamond ring is a rare collector’s piece from Bond Street, masterfully crafted under the William Asprey (WRA) sponsor mark.

Measuring 6.04 x 5.63mm, the central stone is entirely untreated with no fluorescence, featuring a laser-engraved GIA serial number on the facet for absolute verification. The centerpiece is framed by a halo of natural, untreated pink diamonds—gemstones of exceptional rarity. This limited-edition design gained prestigious recognition in the luxury engagement editorials of both Vogue and Harper’s Bazaar. Metal: Fully hallmarked 18ct Gold.
