Huge, 8.7" Amethyst Crystal Point - Brazil

This is a huge Amethyst crystal point mined in the Minas Gerais region of Brazil. The bottom on the point has been cut flat so that it stands up on it's own creating for a very impressive display. The facets of the crystal have had some polishing work done to them.

Amethyst is a purple variety of quartz (SiO2) and owes its violet color to natural irradiation, iron impurities, and the presence of trace elements, which result in complex crystal lattice substitutions. It’s considered a semi-precious gemstone, and just two centuries ago was considered to have a value on par with diamonds, sapphires and rubies.

Much of the world’s amethyst comes from extensive deposits in Southern Brazil that have been heavily mined for about a century. The amethyst occurs in large cavities or geodes within volcanic rocks and the coloration and crystal size can vary greatly.
