Estate 8.69 Carat Australian Black Opal Diamond Platinum Ring
This striking ring centers on a large oval Australian black opal weighing 8.69 carats. The stone displays a dark body tone with vivid play-of-color featuring intense electric blue, emerald green, and flashes of fiery red and orange that shift across the surface. It is secured by four sturdy prongs in a sculptural platinum mounting.
Flanking the opal on each shoulder are clusters of round brilliant diamonds totaling 0.37 carats, set in graceful curved arrangements that frame the center stone. The platinum shank features a distinctive twisted design with subtle yellow gold accents visible in the gallery, adding depth and contrast to the white metal. The overall construction is solid and well-proportioned, with a total weight of 17.30 grams.
Crafted for both everyday elegance and special occasions, the ring combines the dramatic color play of a fine Australian black opal with the cool brilliance of diamonds and the durability of platinum. The ring is currently size 7 and can be resized.
Ideal for collectors of opal jewelry or anyone seeking a unique, high-impact gemstone ring.
