Alexandrite, Sources and Localities
Where is alexandrite mined? There is virtually no alexandrite coming from Russia these days. Between 1833 and 2008, Alexandrite has been discovered not only in Russia but in Australia, Brazil, India, Madagascar, Myanmar, Sri Lanka, Tanzania and the US. This list may seem long, but the production of top quality alexandrite from any of these mines has been relatively small. Currently, the best alexandrite comes from the Hematita mine in Brazil.
