Exceptional Natural Purple Star Sapphire set in Wide 18k Ring

Bold and distinctive, this mid-century ring showcases the rare beauty of a purple star sapphire in a striking, sculptural setting. Crafted in 18k yellow gold, the design features a smooth cabochon sapphire that reveals a luminous six-ray star when viewed in the light—an effect known as asterism.

The sapphire displays a soft, violet-toned hue with a silky surface that enhances the star effect, giving the stone a captivating, almost ethereal presence. Set within a fluid, modernist mounting, the ring is accented by a single diamond that adds a touch of brilliance and contrast.

With its substantial feel and clean, unisex styling, this circa 1960s piece embodies the era’s love of organic forms and bold gemstones—a rare and collectible ring, perfect for those drawn to unique sapphires and standout vintage design.
