Vintage Illusions-Setting Diamond Engagement Ring

This item is a vintage-style solitaire diamond engagement ring, featuring a round brilliant-cut center diamond. The diamond is secured in a classic 'illusion' or 'miracle' setting, which uses a faceted metal plate around the stone to enhance its perceived size and brilliance. The mounting appears to be crafted from a white metal, likely 14k white gold or platinum, though hallmark verification is required. The ring shank is a traditional tapered rounded band with a high-polish finish. The design aesthetic is characteristic of the mid-20th century (circa 1940s-1960s), where illusion heads were popular for maximizing the appearance of smaller diamonds. Based on the photograph, the stone shows good clarity and life, though exact carat weight and color grade would require professional measurement. The condition appears fair to good; there is visible surface wear and minor micro-scratching on the band consistent with daily wear. The prongs appear intact, but the setting shows slight dulling of the metal plate, common in vintage pieces with varied patina. No overt signs of resizing or structural repair are visible from this angle. The craftsmanship is typical of mid-century mass-market fine jewelry, designed for durability and daily use.
