Mid-Century Star Ruby and Diamond Halo Pendant Necklace

This is a vintage Mid-Century pendant necklace, circa 1950s-1960s, featuring a prominent central star ruby and a diamond halo. The pendant showcases a round, cabochon-cut star ruby with a deep purplish-red hue, exhibiting a visible six-rayed asterism under direct light. The ruby is securely held by multiple delicate prongs and is encircled by a classic halo of small, round-cut diamonds set in yellow gold. Based on provided metadata, the mounting and the accompanying fine-link chain are crafted from 14k yellow gold. The star ruby appears to have a slightly translucent quality with natural internal inclusions characteristic of genuine corundum. The diamonds appear to be single-cut or early brilliant-cut stones, consistent with jewelry manufacturing from the mid-20th century. The piece is finished with a simple tapered bail. In terms of condition, the gold shows a light patina and minor surface scratches consistent with careful wear over several decades. No significant chips are visible on the gemstones, though the ruby shows a smooth, polished surface with characteristic silk inclusions. The overall craftsmanship reflects the elegant, high-quality aesthetic of the post-war jewelry era.
