Art Deco platinum, sapphire, and diamond ring. At the heart of this ring is a magnificent blue sapphire, securely held in place by compass prongs. Blue sapphires, known for their depth and allure, were highly coveted during the Art Deco period, and this sapphire is a testament to the timeless appeal of these gemstones. Elongated baguette-cut diamonds add a layer of brilliance to the design, accented by fine milgrain detail. What truly sets this ring apart is its dazzling profile, where round brilliant cut diamonds frame the center stone in an antique "hidden halo" design.
