7.9" Muscovite On White Albite Association - Brazil

Here is a large, beautiful cluster of muscovite crystals that are associated with white albite, collected from Brazil. The specimen is just over 7.9" long and displays eye catching non-metallic luster.

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