Embrace the allure of timeless elegance with this Vintage Platinum Opal and Diamond Halo Cocktail Ring. At its heart is an enchanting 8.45-carat opal, exuding a mesmerizing play of colors that shift beautifully with the light. Surrounding the opal, a halo of brilliant diamonds adds a striking contrast and sparkle, with a total diamond weight of 0.70 carats. This arrangement amplifies the opal's beauty, creating a dramatic and luxurious effect.
Crafted in PT900 platinum, this piece embodies the sophistication of mid-century jewelry design, a nod to the retro vintage era. The choice of a halo setting with baguette and round-cut diamonds evokes a classic glamour, making it perfect for anyone with a love for bold, vintage-inspired pieces. Whether you're adding to a fine jewelry collection or seeking a statement piece, this ring promises elegance, intrigue, and a timeless aesthetic.

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!
