2.5" Lazurite and Muscovite in Marble Matrix - Afghanistan

This wonderful specimen contains lazurite crystals and mica var. muscovite crystals that are partially exposed from a 2.5" wide marble/calcite matrix. This specimen was collected from the Sar-e-Sang District of Afghanistan, an area well known for its phenomenal lazurite crystals.

Comes with an acrylic display stand.

Lazurite is a vibrant blue mineral of the tectosilicates group, with the chemical formula Na6Ca2Al6Si6O24S2. It is the blue component in Lapis Lazuli and is most often found in massive forms, though in some cases it does form individual crystals. There is a location in Afghanistan that is well known for producing phenomenal lazurite crystals in a marble matrix. These specimens are highly sought after by both amateur and expert mineral collectors.

Muscovite is a phyllosilicate mineral of aluminium and potassium. It has a highly perfect basal cleavage yielding remarkably thin laminæ which are often highly elastic.
