A: On the left: Aphrodite standing to front, wearing a mantle and wringing out her hair. On the right: armoured male figure (Ares) standing to front, facing left. He is wearing a helmet on his head, and holding a shield in his right hand, in his left hand a long spear. Between the two figures’ heads: a crescent and three eight-pointed stars underneath. Another eight-pointed start at Aphrodite’s feet, on the left.
Inscriptions: on the left side of Aphrodite: ιαω. Above Ares' head: ι. In the field: ωθ → Perhaps: Ἰ<άω>, <Σαβα>ώθ.
The right side of the gem is broken, on the right side of Ares the fragment of another inscription.
B: Unintelligible pseudo-inscription in five lines.
C: ωαθαναλβ → variant of Ἀβλαναθαναλβα-palindrome?
