In the modern era, only a handful of natural green diamonds have appeared at auction, and most exhibit a bluish or yellowish secondary color. Among the rare exceptions was the 5.03-carat Aurora Green, which achieved more than $16.8 million at Christie’s Hong Kong in 2016, setting world records for a green diamond and earning more than $3.3 million per carat \u003cbr\u003e\u003cbr\u003e \u003ca href=\"http:\/\/library.rauantiques.com\/Report_32-20212.pdf\" target=\"_blank\"\u003eDownload the GIA Monograph and Reports\u003c\/a\u003e","brand":"M.S.

Their pairing—crimson and royal blue—creates a dynamic interplay that recalls Bulgari’s celebrated mid-century color aesthetic. Both gems are documented by the American Gemological Laboratories as natural stones of Burmese origin with no gemological evidence of heat treatment, an exceedingly scarce combination. The stones are framed by approximately 1.50 carats of brilliant diamonds, further heightening the composition’s luminosity. Set in platinum. \u003cbr\u003e\u003cbr\u003e Founded in Rome in 1884, Bulgari ranks among the most influential houses of the 20th century, renowned for its architectural forms, innovative color juxtapositions and uncompromising gemstone selection. The firm’s use of important rubies and sapphires—particularly untreated stones from Burma—became a hallmark of its design language and helped cement its reputation among elite collectors worldwide. \u003cbr\u003e\u003cbr\u003e \u003ca href=\"http:\/\/library.rauantiques.com\/Report_32-2102.pdf\" target=\"_blank\"\u003eDownload the Report\u003c\/a\u003e","brand":"M.S.
