Sterling Silver Black Onyx Oval Men's Ring Size 11.5

Elevate your collection with this striking, authentic vintage statement ring, masterfully handcrafted in heavy .925 sterling silver. At the heart of this estate piece sits a magnificent, high-dome round cabochon of natural Golden Sheen Obsidian.  In ambient light, the stone presents a mysterious, deep velvety black finish. However, when touched by direct light, it reveals a breathtaking, metallic golden celestial shimmer trapped within the volcanic glass—a phenomenal optical effect caused by microscopic gas bubbles from ancient eruptions.  Design & Craftsmanship:  Artisan Border: The prominent cabochon is framed by a meticulous, hand-twisted rope border, a classic mark of premium vintage silversmithing.  Time-Honored Patina: The reverse side bears the classic STERLING 925 hallmark, surrounded by a rich, authentic aged patina that highlights its true vintage provenance.  Premium Substantial Fit: Offered in a rare, substantial unisex size 11.5, this ring provides a bold, commanding presence on the hand while remaining exceptionally comfortable for daily wear.  Specifications:  Metal: Solid Sterling Silver (.925 Purity Hallmarked)  Gemstone: Natural, AAA-Grade Golden Sheen Obsidian (Round Cabochon)  Ring Size: 11.5  Condition: Excellent vintage estate condition with natural, unpolished patina.  Add a piece of Earth's history to your jewelry wardrobe. Ready to wear or gift.
