Star Sapphire and Diamond Ring, 10.0 Carats
A luminous 10.0-carat star sapphire shines at the center of this impressive ring displaying a subdued gray hue with a hint of blue. The glowing cabochon gem rests in a 14k yellow gold mounting between a pair of triangle-framed round diamonds in contrasting white gold. The bold yet understated setting features a textured brushed gold finish adding unique interest.
The stunning optical show in this sapphire is due to a gemological phenomenon called asterism. Appearing in such gemstones as sapphires and rubies, asterism occurs when intersecting fibers within the gemstone project corresponding intersecting rays of light on the surface of a cabochon dome. The rare natural phenomenon gives the wearer the magical view of a star moving across the gemstone’s surface.
