{"product_id":"cats-eye-alexandrite-ring-4-16-carats","title":"Cat's Eye Alexandrite Ring, 4.16 Carats","description":"This extraordinary ring centers a 4.16-carat cat's-eye alexandrite, among the rarest and most coveted gemstones. Named for the luminous band of light that glides across its surface, resembling a feline pupil, the cat's-eye effect is an exceptionally uncommon phenomenon in alexandrite and requires both remarkable crystal structure and expert cutting to achieve. A specimen of this size is particularly noteworthy. \u003cbr\u003e\u003cbr\u003e Adding to its rarity, the alexandrite displays the gem's celebrated color-change effect, shifting from green in natural daylight to a warm brown-purple hue under incandescent light, as confirmed by its accompanying GIA report. Alexandrites exhibiting both a strong color change and a distinct cat's-eye effect are prized by collectors for their exceptional scarcity and beauty. \u003cbr\u003e\u003cbr\u003e The striking design is completed by a double halo surrounding the center stone, set with 1.37 carats of carefully matched alexandrites and 1.73 carats of white diamonds. Set in platinum, the ring showcases one of nature's most remarkable gemological treasures. \u003cbr\u003e\u003cbr\u003e \u003ca href=\"http:\/\/library.rauantiques.com\/Report_32-2793.pdf\" target=\"_blank\"\u003eDownload the Report\u003c\/a\u003e","brand":"M.S.
