Platinum 4ct Opal and 0.67ctw Diamond Halo Cocktail Ring

This stunning platinum opal and diamond halo ring is in excellent pre-owned condition and ready to ship!

Opal has captivated jewelers for centuries, and it's easy to see why. Unlike any other gemstone, opal doesn't reflect light — it refracts it, breaking white light into cascading spectral colors that shift and dance with every movement of the hand. This particular stone displays a vivid play-of-color spanning deep greens, warm oranges, and flashes of blue across an oval face of approximately 4 carats. Set in a low bezel mount of Pt900 platinum, the opal is cradled securely while remaining the undisputed focal point of the ring.

The halo of 24 round brilliant diamonds, totaling approximately 0.67ctw, encircles the opal in a clean, uninterrupted frame. Platinum was the metal of choice for fine jewelry through much of the twentieth century, prized for its density, its bright neutral tone, and its ability to hold stones with minimal prong mass. The Pt900 hallmark stamped on the inner shank confirms the high-purity alloy used here. The result is a ring that reads as quietly refined up close and radiantly colorful from across the room.

At size 6, this ring fits a wide range of wearers comfortably and can be resized by a skilled bench jeweler. It works equally well as a right-hand cocktail ring or as an unconventional engagement ring for the buyer who wants something genuinely one-of-a-kind. Opal engagement rings have seen a meaningful resurgence in recent years, and pieces set in platinum with diamond halos like this one are among the most sought-after expressions of that trend.
