14K Rose Gold 10 Carat Ethiopian Opal and Diamond Halo Ring - Size 10

A freeform Ethiopian opal, weighing approximately 10 carats, centers this 14-karat rose gold ring with a round brilliant diamond halo. The stone carries broad flashes of green, red, and gold across its surface, set high in gold prongs that let light reach it from every side. Opal's shifting color comes from microscopic silica spheres inside the stone that diffract light into these separate flashes, a structure unique to precious opal. Its raised profile and tapered band give it a bold, cocktail-ring presence on the hand.
