Tanzanite Ring in 950 Silver, Oval Cabochon, Argentine Size 19 | Rocas & Cristales

Exclusivity & Design — Ring with Tanzanite: Hand-forged in high-purity 950 silver at our Córdoba, Argentina studio, this authored ring is built around a hand-polished oval tanzanite cabochon, 9 x 7 mm, in Argentine size 19. Its intense blue-violet hue belongs exclusively to stones drawn from the slopes of Kilimanjaro in Tanzania, making every cabochon a hand-selected rarity rather than a routine setting. Please note that ring sizing follows the Argentine standard; we invite you to reach out before purchase if you would like guidance finding your fit.

Aesthetic Details — Ring with Tanzanite: Tanzanite is prized for its exceptional pleochroism, shifting from deep blue to vivid violet as the light source changes. The 950 silver setting frames the stone with elegant restraint, an intentionally quiet mount that lets tanzanite's extraordinary color remain the undisputed focus of the piece.

Craftsmanship & Shipping — Ring with Tanzanite: Hand-crafted in Córdoba, Argentina, this ring carries our full quality guarantee, and ships complimentary to anywhere in the world. Each piece passes an artisan quality check before it leaves the workshop, confirming the polish, the setting, and the authenticity of the natural stone.

Natural Stone Properties — Ring with Tanzanite: Among the rarest gemstones on earth, tanzanite is mined in a single narrow band of land at the foot of Kilimanjaro, discovered only in 1967 and estimated to be roughly a thousand times scarcer than diamond. It is traditionally linked to the third eye and throat chakras, regarded as a stone of elevated spiritual transformation that sharpens intuition, encourages honest communication, and steadies one's connection to purpose. Its trichroism — the ability to reveal blue, violet, and burgundy depending on the viewing angle — is virtually unmatched among natural stones. Tanzanite carries an affinity with Sagittarius, and makes an equally considered gift or an everyday heirloom in the making, its symbolic weight matched by the craft of Córdoba goldsmithing behind it. Each piece we send out is packed with the same care that went into making it, ready to travel to wherever its new owner calls home.
