Vintage Three-Stone Sapphire and Diamond Ring

A classic vintage three-stone ring, likely from the mid-20th century, featuring a central round-cut blue sapphire flanked by two round-cut diamonds. The sapphire displays a deep, saturated cornflower to navy blue hue, set within a white metal mounting that appears to be either 14k/18k white gold or platinum. Each stone is secured by multiple thick prongs integrated into a decorative, openwork gallery. The side diamonds show significant brilliance, suggesting a quality cut such as an Old European or Modern Brilliant. The metalwork features scrolling open designs on the gallery beneath the stones, characteristic of early-to-mid 20th-century craftsmanship. Regarding condition, the metal shows a soft patina and fine surface scratches consistent with light wear. The prongs appear intact, though a professional cleaning and tightening would be recommended for long-term security. No obvious chips or fractures are visible on the gemstone facets in the current view. This style of ring, often referred to as a 'trilogy' ring, represents past, present, and future, making it a popular choice for anniversaries or engagements during the Art Deco and Retro periods.
