About the Setting
The setting is an elaborate shield-shaped 18K white gold mounting with a beaded milgrain border that frames the entire face, evoking an antique medallion aesthetic. A double row of pavé-set round brilliant diamonds encircles the center stone in a glowing halo, while four trillion and round rubies set in yellow gold prongs punctuate the composition at the cardinal points for a vivid color contrast. The gallery features an open filigree scrollwork construction that is as breathtaking from the side and back as it is from the top.
About the Center Stone
The 4.05 carat padparadscha sapphire is among the rarest and most coveted varieties of colored gemstone in the world — a certified unheated stone from Sri Lanka displaying the prized pinkish-orange hue that places it in an elite category above standard pink or orange sapphires. GRS Labs, one of the world's foremost gem laboratories, has confirmed both the padparadscha color classification and the absence of any thermal treatment, a distinction that dramatically elevates the stone's rarity and value. Featuring the classic warm peachy pink of the padparadscha, this is an exceptionally rare and true collector-level acquisition.

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!
