Vintage Filigree White Metal Ring with Round Brilliant Cut Stone

This is a vintage-style ring crafted in a polished white metal, likely sterling silver or white gold, though no hallmarks are clearly legible in the photograph. The central focus is a prong-set round brilliant cut clear stone, which could be a diamond, cubic zirconia, or white sapphire. Flanking the center stone are two smaller clear stones, also prong-set, integrated into an ornate filigree or scrollwork shoulder design. The band features a tapered cathedral-style shank with decorative scalloped or leaf-like motifs that transition into a smooth, thin circular band at the bottom. The construction appears to be cast with hand-finishing on the delicate openwork areas. Noteworthy details include the raised setting which elevates the central stone to catch the light. Regarding condition, there is visible surface wear and fine scratches on the metal consistent with age and frequent use. There appears to be a slight dullness or oxidation to the metal and some buildup around the stone settings, suggesting it needs professional cleaning. The style is reminiscent of Art Deco or mid-century modern aesthetic, likely dating from the mid-20th century to the late 1990s. The overall craftsmanship shows moderate quality with attention to the decorative scroll accents on the gallery.
