Unsure when made, I bought this ring in the 90’s. Solid metal, unsure of the composition, but it’s not a pewter casting, as it’s too heavy for that. Probably stainless steel as there is no tarnish. It’s been turned from the inside as there are tracking marks. UNISEX Please check sizing. I have quite slim fingers, and too big for any finger. A couple of marks here and there from use, only seen in certain light.( see photo 6 in full light) Size( inner) 2cm diameter
