Greek Key Design Bone Clip Earring Arabic Chandelier Egypt

Lovely clip earrings with a greek key design on the outer rim.  Their some kind of bone - I can say they are not ivory - the "graining" is not there. They are a thin mystery metal (light weight)and have a nice antique patina on the front and a more silvery finish the backside.

The clips on the backside are tight and secure. They measure 3 inches long. The disc are 1 & 1/2 inches wide
