Tourmaline and Mica Schist
This Tourmaline and Mica Schist is a fantastic layered, irregular formation of grey to brown, translucent mica, with stunning green, translucent tourmaline crystals.
The amazing colouration of this tourmaline is a result of the presence of lithium ions in the mineral.
This is a complex and fascinating mineral which would make a great display piece.
