Golden Mica Specimen

Micas are known for their perfect basal cleavage, meaning their ability to split into thin sheets. Mica is mostly silvery, looking like aluminum, but in different circumstances, variations occur. Mica can also be golden, or purple, for example, in which cases it is referred to as muscovite, or lepidolite.

This golden muscovite specimen comes from Minas Gerais, Brazil. When it forms in a cluster, the sheets going in many different directions, it is referred to as a golden star muscovite cluster.
