The prominent crown features a large, rectangular step-cut synthetic aquamarine or fine blue glass paste gemstone, delivering a vibrant, icy blue hue. The impressive focal stone is securely held by four prongs within an elegant, finely detailed openwork gallery showcasing classic Art Deco scrolled motifs. The ornate setting transitions into a smooth, simple band, clearly stamped with an authentic 830 silver purity hallmark on the interior.
