The one of the largest mines of amethyst is located near the border between Bolivia and Brazil. One interesting feature is that the heated amethyst that was turned into citrine can restore its purple color if irradiated by X rays. Natural citrine is quite rare, and the majority of citrine stones today in the mineral stores is obviously originating from amethyst. Under high temperature, amethyst changes its violet color to yellow (read citrine), and with specimens from some special regions of the world, it can change color to green (thus green amethyst). Our personal opinion is that the modern interpretation of the color origin in various minerals is deficient and cannot fully describe the actual complex physical picture. Now we believe that it has to do with iron impurities, and probably a role is played by aluminum as well. At first it was attributed to traces of manganese, then some experts claimed that it was of organic origin. The origin of amethyst’s color is still a sort of mystery.

Like all the other quartz minerals, amethyst belongs to the group of Tektosilicates, which is to say that the most fundamental SiO4 structure units are distributed with respect to each other in 3D complex chains and frameworks. Usually the stripes are V shaped producing a form generally known as chevron amethyst. If the stone is not transparent, white stripes are sometimes observed. The color of amethyst is light to dark purple, sometimes, but very rarely one can find green amethyst and more often lavender or pink amethyst. Its hardness is 7 on the Mohs scale of hardness of minerals. The chemical composition of Amethyst is SiO2, which is to say that amethyst is a type of quartz, or the other name for quartz - silica.
