单词	oriental emerald
释义	oriental emerald noun : a green corundum used as a gem In a way this is odd, since, unlike rubies and sapphires, today's commercial emeralds are a green-tinted form not of corundum but of beryl, a different mineral entirely. Yet there is a green corundum, too, known commercially as “Oriental emerald,” which was not distinguished from green beryl in antiquity. ‘Philologos’, The Jewish Daily Forward, 14 May 2004 Word History First Known Use 1802, in the meaning defined above
