Brass "Antique" Chunky Art Deco Style Ring

Estate find. Unsure of stones or actual metal. Appears to be brass, due to the signs of fade on inner and back of ring. Also, heavy in weight. Overall structure is solid and has been polished. Maintained. Good solid condition. Rather large ring. Measures about a size 9. *Model is a size 4.5 so ring is large on her hand/finger. Inquiries welcome.
