Vintage Heart-Cut Blue Sapphire and Diamond Gold Ring

This is a vintage yellow gold cocktail ring estimated to be approximately 40 years old, placing its origin in the mid-1980s. The centerpiece features a heart-cut natural blue sapphire, approximately 0.50 to 0.75 carats, which displays a medium-light cornflower blue hue with visible translucency. The sapphire is held in a traditional prong setting. Flanking the center stone are two small round brilliant-cut diamond accents, likely in the 0.01-0.03 carat range each, which add a subtle sparkle to the shoulders of the band. The band itself is crafted from yellow gold (likely 10K or 14K) and features a split-shoulder design with delicate textured detailing near the setting. The craftsmanship is characteristic of commercial fine jewelry from the late 20th century, favoring romantic motifs like the heart shape. The condition appears fair to good; there is visible surface wear and slight thinning of the shank consistent with decades of use. The metal shows a warm patina but could benefit from professional cleaning and prong inspection to ensure stone security. No specific manufacturer marks are visible in the image, but the style is consistent with high-street jewelers of the 1980s era.
