{"product_id":"ceylon-star-sapphire-ring-untreated-41-85-carats","title":"Ceylon Star Sapphire Ring, Untreated, 41.85 Carats","description":"This exceptional ring displays a Ceylon sapphire with a brilliant star shining in its center. The exceptionally rare 41.85-carat cabochon is verified by the GIA as being completely free of heat treatment and of prestigious Ceylon origin. Sapphires from Ceylon—modern-day Sri Lanka—are among the most sought-after in the world, prized by collectors for their radiant blue hues, remarkable clarity and historic prestige. This example displays both the ideal blue and stunning brilliance of Ceylon sapphires without the assistance of heat treatment, an exceedingly rare find on the contemporary market. \u003cbr\u003e\u003cbr\u003e This gem's six-pointed star detail is the result of a rare optical phenomenon called asterism, caused by perfectly aligned, microscopic titanium dioxide fibers within the ruby. This creates the iconic star flare that appears to dance across the surface under a direct light source. Pairing the iconic luminous blues of Ceylon sapphires with the exceptional star detail makes this gem both extraordinarily beautiful and incredibly rare. \u003cbr\u003e\u003cbr\u003e The central gem is haloed by approximately 1.00 carat of round white diamonds, which continue onto the band, highlighting the sapphire’s brilliance and completing the design with refined elegance. Set in platinum. \u003cbr\u003e\u003cbr\u003e \u003ca href=\"http:\/\/library.rauantiques.com\/Report_32-2386.pdf\" target=\"_blank\"\u003eDownload the Report\u003c\/a\u003e","brand":"M.S.
