Aventurine is a rough quartz that obtains its green, sparkling appearance from deposits of fuchsite (chromium mica). Aventurine received its name in the 17th century from the Italian 'a ventura', meaning 'randomly', which refers to its randomly deposited mica platelets. Aventurine is sometimes called Indian jade, or the stone of heaven. It was known as the gambler's stone because it is the luckiest of all stones in games of chance, and was often placed in charm bags to bring good fortune and money to the owner.
