16.5" Dark Purple Amethyst Cluster - Large, Sparkly Points

This is a truly spectacular cluster of amethyst crystals that was collected from Minas Gerais, Brazil. It consists of large, lustrous, deep purple amethyst crystals that haven't undergone any polishing. The majority of these crystals contain golden-brown goethite sprays, giving the amethyst a speckled appearance. It measures roughly 16.5" wide and weighs just over 59 lbs!

There is some minor chipping to one of the terminations, along with the typical damage around the periphery of the cluster where it was extracted from the pocket.

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 is 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.
