It is usually transparent and best known for its violet colour. Even though it is a form of quartz, it has more iron oxide (Fe2O3) than any other kind of quartz.[1] Because of this, some experts think that its color comes from the iron in it.[1]
Heating the amethyst either takes away its color or changes it to a yellow hue. Amethysts are found in Brazil, Uruguay, Canada (Ontario) and America (North Carolina). The rock amethyst is the birthstone of the month February. In the Mohs scale, it has a hardness of seven.[2]
