Mineral Description
healing crystals

Muscovite in white feldspar specimens mined by Kidz Rocks from Hemet, CA. The white and silver contracting minerals in these specimens is very pretty indeed!

You will receive one specimen from 2 1/2 inches to 3 1/2 inches and weighing between 5 ounces and 8 ounces.

Bulk Purchase Specimen
You are buying one rock. You will receive one rock like the ones in the photographs, not the exact rocks shown. Photographing and listing every crystal separately adds a lot in labor costs. We pass that savings on to you with lower prices and higher quality than the competition.

Muscovite is a common rock forming mineral and is found in igneous, metamorphic and detrital sedimentary rocks. Muscovite has a layered structure of aluminum silicate sheets weakly bonded together by layers of potassium ions. These potassium ion layers produce the perfect cleavage of muscovite. Although it has such easy cleavage, the cleavage sheets are quite durable and are often found in sands that have undergone much erosion and transport that would have destroyed most other minerals. The sheets of muscovite also have high heat and electrical insulating properties and are used to make many electrical components. Muscovite sheets were used for kitchen oven windows before synthetic materials replaced them.

Muscovite is not often valuable as a mineral specimen but is often associated with other minerals of extraordinary beauty and value. Some very nice muscovite crystals accompany such valuable minerals as tourmaline, topaz, beryl, almandine and others. A rare twin variety from Brazil forms yellow five pointed stars and is called Star Muscovite. A deep green variety is called fuchsite and is colored by chromium impurities.


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.


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.
