Cyanotrichite

Cyanotrichite is a rarealuminum copper hydrous sulfate mineral that crystallizes in the form of fibrous aggregates, acicular crystals, and druzy coatings. It was first documented in Banat, Romania in 1839 by E. F. Glocker. He chose to name it after the Greek words kyaneos for "blue" and triches for "hair".

Cyanotrichite was also given the name “Lettsomite” around the same time, after William Garrow Lettsom, a British diplomat, scientist, and author. The color of this crystal can range from light to dark blue and is normally found associated with other copper-bearing minerals such as Malachite, Brochantite, Azurite , and Chrysocolla. You can find major deposits of Cyanotrichite in South Africa, Italy, Germany, France, Austria, and the USA. Our materials come from the Qinglong (Dachang) mine in Guizhou Province in China which yields some of the best material of this kind.
