Vintage Diamond and White Metal Engagement Ring Set

This item is a vintage-style bridal ring set, likely a fused wedding and engagement ring or a 'slotted' jacket design, crafted in a white metal such as 10k or 14k white gold, or possibly platinum. The center features a round brilliant-cut or transitional-cut diamond held in a prominent four-prong 'illusion' or 'miracle' head setting, which is designed to make the center stone appear larger. Flanking the center stone are two rows of smaller accent diamonds, potentially single-cut, pavé-set along the shoulders of the graduated band. The construction features a split-shank appearance near the head, characteristic of Mid-Century Modern or late Art Deco influence, suggesting an estimated age from the 1940s to the 1960s. The metal exhibits a polished finish with minor surface abrasions and light scratches consistent with regular wear and age. The interior of the shank is not visible, so stamps for karat or maker's marks cannot be confirmed. The prongs appear to be intact, though one may show slight rounding from wear. The overall craftsmanship reflects mid-20th-century commercial jewelry production, emphasizing a decorative and substantial silhouette.
