In daylight, the gemstone displays a vivid bluish-green hue that transforms to rich purple under incandescent light. The oval gemstone is entirely untreated, as confirmed by its accompanying GIA report. Set in platinum with two accent diamonds totaling 0.89 carat, this extraordinary ring showcases one of the world’s most coveted gemstones. \u003cbr\u003e\u003cbr\u003e Alexandrite was first discovered in Russia’s Ural Mountains in the 1830s, but Brazil has since produced some of the finest examples. Among the most famous is the 17.08-carat Whitney Alexandrite, housed in the Smithsonian’s National Gem Collection. Like the present stone, it shifts from bluish-green in daylight to intense purple under incandescent light. With its exceptional color change, Brazilian origin and completely untreated condition, this gemstone is a remarkable treasure. \u003cbr\u003e\u003cbr\u003e \u003ca href=\"http:\/\/library.rauantiques.com\/Report_32-2395.pdf\" target=\"_blank\"\u003eDownload the Report\u003c\/a\u003e","brand":"M.S.
