Vintage Opal and Diamond Ballerina Halo Ring

This is a vintage-style cocktail ring features a central oval-cut cabochon opal with a white base color and vibrant pinfire play-of-color, predominantly displaying green and subtle pink flashes. The opal is secured by six yellow gold prongs within an elaborate 'ballerina' style tiered halo setting. This mount consists of a surround of tapered baguette-cut stones, likely diamonds or high-quality stimulants, arranged in an undulating radial pattern to mimic the movement of a tutu. The primary metal appears to be yellow gold, possibly 10k or 14k based on typical mid-to-late 20th-century jewelry construction (circa 1960s-1980s). The craftsmanship displays a complex multi-level basket gallery designed to elevate the focal stone for maximum light exposure. Visible condition includes some surface wear on the metal and minor buildup between the accent stones, which is standard for an estate piece. The opal surface appears smooth without significant crazing, though its specific origin (likely Australian) would require forensic gemological testing. The overall design is classic Mid-Century Modern to late vintage glamour.
