The exceptionally rare royal blue star sapphire is certified by C. Dunaigre as completely free of heat treatment and of prestigious Ceylon (Sri Lanka) origin. Accented by 2.54 carats of white diamonds and set in platinum, this ring unites an extraordinary gemstone with the unmatched craftsmanship of Oscar Heyman. \u003cbr\u003e\u003cbr\u003e This gem's trademark six-pointed star is the result of a rare optical phenomenon called asterism, caused by perfectly aligned, microscopic titanium dioxide fibers within the sapphire. This creates the iconic star flare that appears to dance across the surface under a direct light source. \u003cbr\u003e\u003cbr\u003e Founded in New York in 1912, Oscar Heyman is a high-end American jeweler renowned for uniting exquisite artistry with an expert eye for extraordinary gemstones.
