The oval gem is engraved with a dancing satyr, depicted nude with an animal skin draped over his raised right arm, his small tail visible behind, with a thyrsus in front of him. The gem is set in a substantial gold ring in an arts and crafts style, probably Edwardian, an engraving on the inside for Ali Girardet (?)
English private collection, mounted in the 19th to early 20th century
