Vintage 17k White Gold 9.75tcw Opal and Diamond Cocktail Ring

A striking vintage ring crafted in 17k white gold, centered with a substantial 9.75 carat opal cabochon and framed by approximately .80 carats total weight of diamonds. The opal is cut in an elongated oval form with a high, smooth dome, allowing its surface to display broad, fluid fields of color.

The play of color is dominated by vivid blue and green flashes that move across the stone in layered, ribbon-like patterns. These saturated tones shift dynamically within the cabochon, creating depth and visual dimension beneath the polished surface. Surrounding the opal, round brilliant-cut diamonds are arranged in a radiating halo. Each diamond is individually set in sculpted prongs that extend outward from the center, forming a balanced, crown-like frame. The bright white brilliance of the diamonds provides a crisp contrast to the opal’s saturated blues and greens, while the white gold mounting reinforces the cool tonal harmony of the design. The gallery is thoughtfully constructed with openwork supports that elevate the center stone, and the band tapers smoothly from the setting for a clean, substantial profile on the hand. Bold in scale yet refined in execution, this ring showcases the natural character of the opal within a confident, architectural setting.
