New vintage silver cocktail 925 ring

New vintage silver cocktail 925 ring Quick list Measurements to follow Simple minimalist modern industrial rustic design! Great craftsmanship! Thin hammered metal ring featuring 4 large bands. Looks like a helmet or mask (with some imagination 😀👍). The important thing is it looks stunning on any hand (even fat wrinkly ones like mine!😀👍) New vintage c. 1970s. Probably handmade in Mexico (because of the design, craftsmanship, aesthetic) Genuine silver. Hallmark: 925 + MMA (?) + “1” in a symbol denoting region or craft centre. Note: this was black so I polished it with toothpaste. Group photos show the variety in the collection
