Size 6. This solid sterling silver ring features a textured, cast Brutalist design from the Neptune collection by Studio C&K. The interior shank is clearly stamped with the maker mark and collection name, confirming its mid-century origin. Weighing a substantial 12.0 grams, the piece displays deep oxidized recesses that accentuate its organic, craggy form.Good vintage condition with light surface scratches and minor scuffing to the raised polished areas. The original dark patina in the recesses is largely intact.
