Adjustable Ring in 950 Silver with Rainbow Obsidian Cabochon | Rocas & Cristales

Exclusivity & Design — Ring with Rainbow Obsidian: Hand-forged in 950 silver at our Córdoba, Argentina studio, this one-of-a-kind ring channels the quiet philosophy behind every Rocas & Cristales piece: noble metal in dialogue with the silent force of natural stone. Set as an adjustable cabochon, it begins with a careful, hand-selected piece of rainbow obsidian, so no two rings ever leave the workshop exactly alike. Conceived for those drawn to distinction and authenticity, this sculptural design brings together Argentine goldsmithing tradition and a contemporary, considered sensibility.

Aesthetic Details — Ring with Rainbow Obsidian: Rainbow obsidian carries a singular kind of beauty: its surface catches faceted light in shifting bands of violet, blue, and copper, revealing new depth with every turn of the hand. The hand-set 950 silver mounting lets that natural sheen take the lead, while a hand-polished finish keeps the stone smooth against the skin. Every ring retains the stone's own natural markings, celebrated here as proof of its one-of-a-kind character rather than smoothed away.

Craftsmanship & Shipping — Ring with Rainbow Obsidian: Hand-crafted in Córdoba, Argentina, this piece carries our quality guarantee on both metal and setting. We offer complimentary worldwide shipping, so this quietly luxurious ring can find its way to wherever you call home.

Natural Stone Properties — Ring with Rainbow Obsidian: Technically a volcanic glass rather than a true mineral, obsidian forms when lava cools too quickly for any ordered mineral structure to take shape, a trait that has fascinated cultures across the world for millennia. Its rainbow variety owes those iridescent bands to microscopic inclusions of magnetite and hematite formed during rapid cooling. Sourced from Mexico, this natural stone has long been associated with the solar plexus and root chakras, and traditionally with the sign of Scorpio. Many hold that it encourages emotional clarity, gently drawing hidden patterns into the light and supporting deep, grounded transformation. Worn as a ring, it becomes a quiet companion for introspection — a fragment of ancient volcanic fire made wearable art.
