About Amethyst - History and Introduction
Amethyst is the most precious and valuable stone belonging to the quartz group of minerals, with exception to rare blue-green gem silica.

Without such coloring agents, amethyst would simply be transparent, ordinary colorless quartz. Like other varieties of macrocrystalline quartz, amethyst has transparent to translucent clarity and a vitreous luster. Cryptocrystalline varieties almost always occur with translucent to opaque clarity.

Amethyst is the violet-colored sister stone of golden citrine quartz. Color-zone ametrine is the bi-colored combination of both amethyst and citrine. The only difference between amethyst and citrine is the oxidized level of iron impurities in amethyst. When amethyst is heated at high temperatures of around 470ºC to 750ºC, iron impurities are reduced and can turning violet amethyst into golden 'heated' citrine. Lower grade amethyst stones are often heated to produce golden colored citrine stones. Heated citrine will typically appear more reddish when compared to unheated citrine.
