Foxdale granite muscovite pegmatite

Description: Very coarse, anhedral quartz with aggregations of subhedral muscovite.

Muscovite, also called common mica, potash mica, or isinglass, is abundant silicate mineral that contains potassium and aluminium and is the most common member of the mica group. Because of the way the mineral forms, often in layers, it can occur in thin, transparent, but durable sheets.

Muscovite is pearlescent, which means it can add an additional glittery shine when added to certain paints and ceramic glazes and is often found in cosmetics.

Foxdale was a very important mining areas on the Isle of Man and we have numerous examples of the often beautiful minerals that were extracted there.
