Illusion Mount Ring Appraisal

Vintage Diamond Illusion Mount Engagement Ring

This is a vintage-style engagement ring, likely dating from the mid-20th century (circa 1940s-1950s). The ring features a central round brilliant-cut diamond set within a square 'illusion' head. This design technique was popular during the mid-century to make a modest diamond appear larger and more prominent. The center stone is flanked by smaller accent diamonds—likely single-cuts—set into the shoulders of the shank. The metal appears to be a white-toned alloy, potentially 14k white gold or platinum, though a secondary metal like palladium was also common for this era. The shank is relatively slender and tapers toward the top where it meets the decorative shoulders. Notable craftsmanship includes the 'mirrored' metal plates surrounding the center stone and the decorative milgrain or bead-setting on the side stones. Regarding condition, the metal shows signs of light surface scratches and a dulling patina consistent with regular wear over several decades. The prongs on the central head appear intact but would require a professional jeweler's inspection to ensure security. No visible maker's marks or stamps are discernible from the image, but the style is characteristic of classic American bridal jewelry from the post-war period.
