6.20 CARAT UNTREATED AMETHYST

Amethyst can vary in shades of purple and although this form of quartz must be purple to be Amethyst, the shades can even include a reddish and milky purple quality. The purple colour comes from the existence of manganese in clear quartz. The presence of iron in certain quantities determines the comparative intensity of its colour. Because of it's naturally unparalleled color, Amethyst could be very expensive but due to it's wide-spread availability and numerous global deposits, it can be found very inexpensively. Not only can Amethyst range in colour but it also ranges in transparency from transparent to almost translucent though always maintaining it's glassy luster
