A large Roman green chalcedony intaglio. The Three Graces.

Beautiful ancient depiction of the Three Graces engraved on a large slightly burnt gemstone. On the back, a small chip. In the foreground, a female figure seen from behind turned slightly in three-quarters with her face in profile to the right. In the background, the other two figures: the one on the left holds ears of wheat and poppy flowers, the one on the right a globe; next to it, two small altars.
Beautiful conservation. Slight wear marks.
