Amethyst Crystal Cluster Macro - a photo on Flickriver

A macro photograph of a section of a beautiful Amethyst Crystal Cluster (from a Geode) in my rock and mineral collection.

Amethyst is a purple variety of quartz (SiO2) and owes its violet colour to irradiation, impurities of iron and in some cases other transition metals, and the presence of other trace elements, which result in complex crystal lattice substitutions.

Just like my interest in Astronomy, my interest in Minerals, Crystals, Rocks and Fossils (and Geology in general) is purely scientific.
