Sculpture, Volto di Cleopatra - 38 cm - Stone

Beautiful woman's head, perhaps Cleopatra,
The sculpture is made of stone, perhaps granite; I can't quite recognize the material,
It measures 38 x 30 x 22 cm and weighs 50 kg.
On the back there are two iron hooks.
The head is not perfectly round—this is evident from looking at the back photos; it is flat, surely mounted to a wall.
