Cobalt Spinel Ring, Untreated, 5.23 Carats

Cobalt Spinel Ring, Untreated, 5.23 Carats

This exceptional ring is centered by a cushion cut cobalt spinel weighing an impressive 5.23 carats. The gem is entirely untreated, as confirmed by its accompanying GRS report, and displays a remarkably saturated cobalt-blue hue—among the rarest and most sought-after colors in spinel. Diamonds totaling approximately 1.00 carat further enhance the design, adding brilliance along the band. Set in platinum.

Long admired for their vivid color and captivating luster, spinels have historically been mistaken for rubies and sapphires, even appearing in some of the world’s most important crown jewels—earning them the enduring nickname of the “imposter gem.” Once overlooked, fine spinel has risen dramatically in prominence, with untreated specimens such as this now regarded among the most coveted of all colored gemstones for collectors.
