About This Sapphire:
This exceptional 5.75 carat Burma sapphire displays the coveted royal blue coloration that makes Burmese sapphires the world's most prized. The cushion cut maximizes the stone's natural brilliance while showcasing the distinctive velvety blue that characterizes fine Burma stones. At 11.23 x 9.69 x 5.79mm, this substantial sapphire provides an impressive presence suitable for creating heirloom-quality jewelry. The absence of heat treatment ensures this sapphire maintains its natural rarity and investment value.
About Burma Sapphires:
Burma (Myanmar) sapphires represent the pinnacle of sapphire quality, renowned for their exceptional color saturation and silk inclusions that create the distinctive "sleepy" appearance prized by connoisseurs. The legendary Mogok region has produced the world's finest sapphires for over 1,000 years, with unheated specimens commanding premium prices due to their natural beauty and increasing scarcity. Political restrictions have severely limited supply, making Burma sapphires among the most valuable-colored gemstones in the world.

One of One
Most jewelry is made to be sold many times over. Ours isn't. We source rare vintage and estate watches you won't find in a display case anywhere else, and what we don't source, we make ourselves. Either way, the piece in front of you is singular, not pulled from a production run. When you buy from Assay, chances are no one else on earth owns its twin.
Featured on...
At Assay, we’re proud to be featured as top sellers across multiple marketplaces (1st Dibs, Chrono24, Etsy, Rubylane and more). No matter where you prefer to shop, you’ll find the same exceptional products and service available on every platform!
