Azurite is a popular mineral, typically found as tabular to prismatic crystals of a deep “azure blue” colour. However there are over 45 well-known forms, with over 100 forms described. Azurite is often pseudomorphed to Malachite and the two are very frequently found together.
Copper Chloride Hydroxide
Atacamite is an unusual and attractive halide mineral. It is polymorphous with two other minerals; paratacamite and botallackite. A polymorph is a mineral that shares the same chemistry with other minerals but has a different crystal structure. These three minerals are members of the Oxy-halides Subclass. This subclass of the halide minerals is unique in possessing oxygens and hydroxides in their chemistries.
The Atacama Desert, from where Atacamite gets its name, is one of the driest places in the world. Atacamite has a deep green colour and is often associated with many other rare and colorful minerals such as chyrsocolla, brochantite, pseudomalachite, connellite, linarite, caledonite, libethenite, cornetite, cuprite and malachite. Some of these specimens can be quite beautiful, with a combination of blue, green, and red hues. Atacamite is a wonderful and interesting addition to your collection.
