Delicate detailing and slightly tapered shoulders add vintage charm. Hallmarked with the Swedish triple crown stamp and maker’s mark—a key in a diamond—this piece is likely from the early 20th century. ⭐ Ring Size: UK L 1/2 | US 6 | EU 52 ⭐ Weight: 3.6g ⭐ Band Width: 1.9mm ⭐ Projection: 7.7mm ⭐ Main Gemstone: Turquoise – 14 x 8.2mm, oval cabochon ⭐ Accent Gemstones: 20 Marcasites – 2.1mm each, round cut Turquoise is associated with protection, wisdom & serenity.
