Comment: There is Muscovite and then there is this Muscovite! What an incredible light lime green to yellow green color. It is almost iridescent. Thousands of delicate Muscovite crystals with pearly luster not tightly formed in "books," but blossoming out in all directions. What a beauty! The name of Muscovite comes from Muscovy-glass, a name formerly used for the mineral because of its use in Russia for windows.
Minerals: Muscovite (KAl2(Si3Al)O10(OH,F)2)
