Colorless plate of Natrosilite with perfect micaceous cleavage. It is a phyllosilicate found in nepheline syenite pegmatites hosted in alkalic, differentiated massifs, namely the Kola Peninsula. I have included the water clear plate as a demonstration of its perfect cleavage. It is rare and found only in the Kola Peninsula and at Mont Saint Hilaire. Identified by Dr. Igor Pekov.
