Metaphysical Uses
Muscovite is a member of the mica group, an important component of granite and some schist. The composition of these minerals are hydrous potassium aluminium silicate with a lustre that varies from transparent to pearly. Muscovite occurs as tabular, commonly twinned pseudo-hexagonal crystals often with deep striations on the prism faces. It also occurs as foliated, scaly lamellar masses. Muscovite can be pink, colourless, silver-white, yellowish, greenish with a pearly lustre on cleavage faces. It often has a sparkly look. Because of its silvery sheen, Muscovite is sometimes called cat's silver.
Muscovite is great for inspiring reflection and self assessment. It allows you to reflect on the past and the self objectively, and without fear. It can also help in auric cleansing and unblocking the psychic channels. Muscovite encourages clarity in visions and self reflection. It can be used during times of cleansing or fasting to help reduce hunger pangs, provide energy, relieve dehydration and give a general boost. It can help sufferers of insomnia, night sweats, nightmares, restless leg syndrome and sleep apnoea.
Physical Characteristics
Color: White, silver, yellow, green and brown. 
Luster: Vitreous to pearly. 
Transparency: Crystals are transparent to translucent. 
Crystal System: Monoclinic; 2/m 
Crystal Habits: Tabular crystals with a prominent pinacoid termination. Muscovites four prism faces form diamond shaped "books" and if modified by another pinacoid they form pseudo-hexagonal crystal "books". The sides of the crystal often tend to tapper. Also as lamellar rock forming masses and small flakes in detrital material. Twinned crystals can form flat five pointed stars. 
Cleavage: Perfect in one direction producing thin sheets or flakes. 
Fracture: Not readily observed due to cleavage but is uneven. 
Hardness: 2 - 2.5
Specific Gravity: Approximately 2.8 (average) 
Streak: White 
Associated Minerals: Quartz, feldspars, beryl and tourmalines. 
Other Characteristics: Cleavage sheets are flexible and elastic, meaning they can be bent and will flex back to original shape. 
Best Field Indicators: Crystal habit, cleavage, elastic sheets, color and associations.
