In gemology, Amethyst is recognized as a naturally occurring, purple colored semi-precious gemstone of Quartz mineral family. Green Amethyst on the other hand is not a different gemstone but the outcome of intense heat treatment done to change Amethyst color from purple to green. The term ‘Green Amethyst’ is a misnomer, meaning it is a false identity that misleads people who might be looking for Prasiolite. While both Amethyst and Prasiolite belong to same mineral family, they do not exist as mere color options but completely different gemstones with different market pricing. Since Amethyst is the most valued gemstone of quartz mineral family, people often try to pitch and sell Prasiolite as Green Amethyst for profiteering. The market value of such a heat-treated stone is far less than Amethyst or even Prasiolite.
