Vintage Sterling Silver Ring featuring an oval cabochon green stone (likely jade or aventurine) in a six-prong setting

Vintage sterling silver ring featuring an oval cabochon green stone (likely jade or aventurine) in a six-prong setting. The ring is marked “ST.SIL” (Sterling Silver) on the interior band. The design showcases a bold, modernist style with distinctive geometric cutout triangular shapes on the shoulders of the band, creating an eye-catching architectural aesthetic. The stone displays a rich, deep green color with natural variations and a polished dome surface. This piece shows authentic wear consistent with age and use, including slight tarnishing and minor band distortion, giving it genuine vintage character. The ring measures approximately 19-20mm in internal diameter (approximately US size 9-9.5 / UK size R-S / AU size S-T). The substantial wide band and statement stone make this an impressive unisex piece. Perfect for collectors of vintage sterling silver jewelry or those who appreciate bold, artistic modernist design with a touch of bohemian charm.
