The cushion cut gem displays a vivid green in natural light, shifting to a rich brownish pink under incandescent light. Graded by the AGL as completely natural and untreated, the phenomenal stone showcases its extraordinary properties without enhancement. The degree of color change is rated prominent to strong, with an impressive 80–90% shift, and a color-change quality graded excellent to very good. The alexandrite is accented by 1.75 carats of diamonds and set in 18K yellow gold by the renowned jeweler Carter. \u003cbr\u003e\u003cbr\u003e Though alexandrite was first discovered in Russia’s Ural Mountains in the 1800s, many of the finest examples have since been sourced from Sri Lanka. This Ceylon alexandrite is particularly rare and highly prized by collectors and designers alike for its exceptional clarity, intensity of color and unique optical properties. \u003cbr\u003e\u003cbr\u003e \u003ca href=\"http:\/\/library.rauantiques.com\/Report_32-1044.pdf\" target=\"_blank\"\u003eDownload the Report\u003c\/a\u003e","brand":"M.S.
