Azurite
Mineral: Azurite
Description: Azurites from the ancient collection of Des Cloizeaux. Des Cloizeaux was a professor here at the National Museum of Natural History and is credited with the discovery of microcline feldspar (think Amazonite - probably the most well-known microcline here in the USA). He was probably most well known for his exhaustive study of crystal structure. The mineral Descloizite was named in honor of Des Cloizeaux.
