2.20 Ct. Blue Cobalt Spinel from Vietnam

A rare and arresting presence, this transparent 2.20 carat cushion shape blue cobalt spinel commands attention with precise measurements of 8.52 by 7.05 by 4.21 mm. Cut in a faceted, mixed brilliant cut to maximize fire and scintillation, the stone presents an intense color intensity that plays between deep ocean blue and electrified cornflower, depending on the light. Clarity is graded slightly included, evaluated at eye level, a characteristic that lends personality rather than distraction, and the excellent polish ensures each facet speaks with crystalline clarity. This cobalt spinel is entirely natural, with no enhancement, and its Vietnamese origin adds provenance and story to its already distinguished pedigree. For the collector who values both rarity and resilience, the gem offers substantial presence on the finger without overwhelming proportion, a balance of statement and refinement that only a gem of this caliber can achieve.

Envisioned as the centerpiece of finely tailored creations, this gem adapts effortlessly to an expansive range of custom settings, from a minimalist solitaire ring that honors pure color, to a halo of brilliant cut diamonds that amplifies its cobalt depth. It will translate beautifully into a modern three stone composition flanked by trapeze or tapered baguettes, or into a vintage inspired cluster with filigree shoulders and milgrain detail. For those who favor contemporary restraint, consider a low bezel or tension mount that showcases the cushion silhouette while offering secure wearability. The size and mix of brilliance make it equally compelling in a pendant suspended from a delicate chain, or in a pair of bespoke drop earrings paired with accent sapphires or emeralds for chromatic contrast. For bespoke commissions, we recommend warm yellow gold to emphasize the blue with a luxurious glow, or platinum for a cool, architectural presentation. At The Natural Gemstone Company we collaborate with master jewelers to translate your vision into heirloom quality, advising on metal choice, setting style, and complementary stones to ensure the finished piece reflects refined taste and personal achievement. Owning this cobalt spinel is not merely an acquisition, it is a declaration of discernment and a beginning for a bespoke creation that will be treasured for generations.
