Beautiful Amethyst Crystals on Matrix - Namibia

This is a pristine mineral specimen, containing beautifully formed amethyst crystals on a rocky matrix that's coated in micro-quartz crystals. The 1.4" amethyst crystal on this specimen is incredibly transparent and has almost no damage to any of it faces, however there is a very small chip out of the termination.

Amethyst is a purple variety of quartz (SiO2) that owes its violet color to natural gamma 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. The largest and best known amethyst deposits occur in southern Brazil and Uruguay, where they are found in hydrothermally-formed geodes, but many localities around the world produce an amazing variety of amethyst crystals and formations. They are almost always formed in medium- to high-temperature geological settings.
