Vintage Ethnic Etruscan Style Silver Filigree Dome Ring

A gorgeous ring made with lovely silver filigree and shaped like a dome. It has repousse elements that are used in Etruscan style and Egyptian revival jewelry, but it is unmarked so I can not tell exact origin. The shank is also worked in filigree and it is in good vintage condition, but could do with a polish.

The dome measures 1.8 in diameter (3/4") and around 1.2 cm (1/2") height. Size is 5 1/2. weight is 7 g.
