This extraordinary 5.02-carat cobalt blue spinel is an exceptional rarity among fine gemstones. Of all the known spinels, one species stands above all others—the stunning cobalt blue spinel mined in the Luc Yen Mine in Vietnam. These cobalt colored gems from this mine are unique in the world, distinguished by their rare neon-blue hue that appears to glow from within. Their rarity, unparalleled vibrancy, and luminosity set them apart as some of the most extraordinary gemstones ever discovered. Any clean spinel from the Luc Yen Mine is exceptionally rare, with most weighing between a half a carat and two carats. This example, weighing 5.02 carats, is the only flawless spinel of this size known to exist.

This gemstone has also achieved the highest accolades from the world's foremost gemological authorities, including its Classic Classification by the American Gemological Laboratories (AGL). Only a tiny percent of gems receive this coveted designation of “Classic,” reserved for only the finest examples of their kind. Our spinel proudly holds this esteemed grade. In addition, in the coveted appendix letter from the lab calls this stone “exemplary.” In addition, it has Platinum Rarity Award and Appendix Letter from GRS (Gem Research Swisslab). In their certification, GRS describes this spinel twice as “magnificent,” praising its “very rare combination of size, excellent blue color (GRS Peacock Blue), good brilliance and transparency, as well as balanced proportions.”

Spinel has long captivated collectors and connoisseurs for its brilliance, durability and exceptional range of colors. Mistaken for ruby for centuries, some of history's most famous gems—including the 170-carat "Black Prince’s Ruby" in the Imperial State Crown of England—are actually spinels. Today, the cobalt spinel holds its place as one of the most coveted and intriguing gemstones for fine jewelry, celebrated for its unmatched brilliance and rarity. This remarkable gemstone is set in platinum and rose gold— framed by 1.25 carats of dazzling pink and white diamonds that enhance its radiant beauty. A true testament to the artistry of nature’s wonder and fine jewelry, this ring represents the pinnacle of gemstone rarity and craftsmanship.
