Vintage 1970s Alexandrite Solitaire Ring

This piece is a vintage 1970s solitaire ring featuring a large, round-cut purple gemstone, identified via context as Alexandrite. The stone demonstrates a strong, saturated violet-purple hue in the current lighting, which is characteristic of the 'raspberry' tones often found in synthetic color-change corundum or spinel popular during the mid-20th century. The gemstone is held in a traditional multi-prong setting, likely crafted from 10k or 14k yellow gold consistent with 1970s production styles. The prongs appear to be substantial, securing the large table of the stone which exhibits a high degree of luster and clarity. Physically, the ring has a classic high-profile mounting that elevates the gemstone to allow maximum light entry through the pavilion facets. The band appears to be a standard polished shank. Given the era and the vibrant purple-to-blue-green shift typical of such stones, it is highly probable the specimen is a lab-created variety, which was frequently sold in high-end tourist markets and department stores during the 70s. The condition appears to be fair to good, with the stone retaining sharp facet edges and no immediate signs of major chipping, though closer inspection for minor 'flea bites' along the girdle is recommended. The setting shows normal signs of age-related patina and light surface scratches consistent with occasional wear.
