It’s appropriate that Bayco‘s sapphire ring is dubbed the Ultimate, because I can think of no better way to describe it. The piece, which is set to be on display at JCK’s LUXURY show later this month, is on fire with diamonds: The epaulet diamond sides stand out almost as much as the 22 ct. sapphire center. That sapphire, unheated and hailing from Burma, is cushion cut and glows with a color so rich, it appears as if it could quench a thirst. Micro-pavé sapphires dance around it, further electrifying its glossy exterior. And, of course, it’s set in platinum—only the best for this blue beauty. All of this makes Bayco’s stunner our Jewel of the Month.
