Vintage Silver Modernist Ring 7.5 Freeform Art Sculptural Irregular Handmade

Thanks for stopping in to see this freeform unmarked silver ring. It polishes up like sterling but is handmade and unsigned with no silver marking so I don’t know if its for sure 925 sterling or something less like 850. I really tried to get all sorts of photos so you know just the exact age, use, size, look and feel of it from every angle. Please let me know of any questions at all!
