Platinum Purple Star Sapphire and Diamond ring, 18.55-Carats

A luminous 18.55-carat cabochon star sapphire forms the mesmerizing centerpiece of this elegant mid-century ring. Exhibiting a vivid purple hue and a distinct six-rayed star that glides gracefully across the surface, the sapphire displays the rare optical phenomenon of asterism, a characteristic prized by connoisseurs of fine gemstones.

The celestial gem is surrounded by a scintillating halo of 10 baguette-cut and 22 round brilliant diamonds, totaling 0.70 carats in weight, adding radiance and structure to the soft, glowing body of the sapphire. Crafted in platinum, the setting features an intricate open gallery beneath the stone, revealing a delicate lattice of metalwork that allows light to dance through every facet.

A naturally occurring phenomenon, Asterism occurs when light reflects off very fine, needle-like inclusions of rutile (often referred to as silk) that intersect within the stone. When viewed under a single light source, these fine internal fibers catch and scatter light to form a floating, star-like pattern that appears to move as the gem is turned. The phenomenon imbues the sapphire with an otherworldly depth and sense of life, making each viewing a new discovery.

This ring is currently a size 7 and is sizable to your needs.
