AMETHYST CACOXENITE CRYSTAL CLUSTER
A fantastic sparkly Large Amethyst Cacoxenite Crystal Cluster. I have taken the photos for this under an Autumn morning Sun to show the amazing inclusions. This cluster is deep purple top quality crystals with Cacoxenite inclusions. Beautiful sharp points make this cluster really sparkle and are a mark of its quality. This is a really nice piece of Brazilian Amethyst, not too big for posting but with a large presence. Speaking of which it would make an awesome gift to yourself or someone else deserving of a beautiful ancient treasure.

Quartz is the most common mineral found on the surface of the Earth. A significant component of many igneous, metamorphic and sedimentary rocks.
Amethyst is the purple variety of quartz and is a popular gemstone. If it were not for its widespread availability, amethyst would be very expensive. The name “amethyst” comes from the Greek and means “not drunken.” This was maybe due to a belief that amethyst would ward off the effects of alcohol. Most likely the Greeks were referring to the almost wine-like color of some stones that they may have encountered. Its colour is unparalleled, even other more expensive purple gemstones are often compared to it. Amethyst also comes in green.
Cacoxenite Fe243+AlO6(PO4)17(OH)12 · 75H2O
From the Greek word for “bad” and “guest” due to the fact that the phosphorous content of Cacoxenite lessens the quality of iron smelted from ore containing it. A secondary mineral found in oxidized zones of Phosphatic Magnetite deposits, in novaculites, in phosphate-rich pegmatites, and rarely in iron-rich sediments and soils.
