Caligulas Ring

A 2,000-year-old sapphire ring, often attributed to Roman Emperor Caligula, features a delicate portrait engraved into the stone, widely believed to be his fourth and final wife, Caesonia. Crafting a ring from a single piece of sapphire was an immense technical feat in antiquity.

The Ring:

The Material: It is a hololith, meaning the entire ring (both the stone and the band) was carved out of a single piece of sky-blue sapphire.

The Engraving: The bezel features the profile of a woman, which historians and gem collectors associate with Caligula's empress, Milonia Caesonia.

Current Status: The ring is part of the legendary Marlborough Gems collection. It previously surfaced at an auction through the royal jewelers Wartski.
