Amethyst

Amethyst or amethyst is a kind of quartz mineral rock. . The amethyst is usually purple to pink. In history, purple is a color used by kings, queens, and other members of the royal family. Therefore, the rulers often have diamonds made of amethyst.

Amethyst is a purple variety of quartz (SiO2) and owes its violet color to irradiation, iron impurities (in some cases in conjunction with transition element impurities), and the presence of trace elements, which result in complex crystal lattice substitutions. The hardness of the mineral is the same as quartz, thus it is suitable for use in jewelry.
