  • Amethyst is a purple variety of quartz composed of silicon dioxide (SiO₂).

  • It forms when quartz crystallises from silica-rich fluids, most commonly in hydrothermal veins and in cavities within volcanic rocks such as basalt.

  • Like all quartz, amethyst has a hardness of 7 on the Mohs scale.

  • The purple colour is caused by trace amounts of iron within the quartz crystal structure, modified by natural irradiation from surrounding rocks.

  • This piece is sourced directly from Brazil.
