1.85" Amethyst Crystal Cluster - Madagascar

This is a small, 1.85" cluster of amethyst crystal points. They have excellent color, often darkening the closer to the tip you get. It was collected in Madagascar and makes for an attractive miniature specimen.

The cluster has been mounted to an acrylic display base with mineral tack for optimal presentation.

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.
