Introduction to the Meaning and Uses of Charoite. Microcline is a common mineral found worldwide, the massive form is green and green and cream striped (Albite) in colour. Crystals are roughly tabular parallel to (010) and elongate parallel to the c or a axis. It is thought to treat eye disorders, fevers, water retention, and ease the pain of childbirth. Amazonite Geological Properties Amazonite, also known as "Amazon stone," is a semi opaque blue-green variety of microcline feldspar. Microcline is identical to orthoclase in many physical properties, and can be distinguished by x-ray or optical examination. Charoite is an incredible stone of the Violet Ray with an almost tangible movement of energy flowing in magnificent swirls and eddies of violet, lavender and purple. Microcline forms during slow cooling of orthoclase; it is more stable at lower temperatures than orthoclase. Microcline is usually opaque to translucent, white to pale-yellow in color, and has a vitreous-to-dull luster. ... Microcline. A rare, translucent, orange, gem variety that is included with hematite is known as “sunstone.”. The Spanish explorers who named it apparently confused it with another green mineral from that region. Microcline (KAlSi3O8) is an important igneous rock-forming tectosilicate mineral. Microcline may be chemically the same as monoclinic orthoclase, but because it belongs to the triclinic crystal system, the prism angle is slightly less than right angles; hence the name "microcline" from the Greek "small slope." Cleavages intersect at 90°41'. Amazonite is a mineral of limited occurrence and is present in parts of Brazil, Colorado and Virginia in the United States, Australia and Madagascar. In one direction, it has perfect cleavage, but in another direction, the cleavage is only good, thereby forming almost perfect right angled prisms. It is a potassium-rich alkali feldspar. It stabilizes brain waves and brings clarity to our thoughts. Amazonite is actually called Microcline and is a Potassium, Aluminium Silicate and belongs to the Feldspar Group of Minerals. This crystal helps us purge what we do not want inside of us emotionally. Sanidine is a polymorph of alkali feldspar stable at yet higher temperature. It is a tectosilicate or framework silicate that crystallizes in the triclinic system as frequently twinned, equant crystals with square cross sections. Microcline is believed to be a stone of understanding, cooperation, and clarity. nα = 1.514 - 1.529 nβ = 1.518 - 1.533 nγ = 1.521 - 1.539. Its name stems from the Greek micros, meaning “small,” and klinein, or “slope,” and refers to a small inclination from 90 degrees between its cleavage angles. Microcline may be chemically the same as monoclinic orthoclase, but because it belongs to the triclinic crystal system, the prism angle is slightly less than right angles, hence the name “microcline” from the Greek “small slope.” It is a fully ordered triclinic modification of potassium feldspar and is … a Scientific Opinion of the Panel on Food Additives, Flavourings, Processing Aids and Food Contact Materials from the EFSA. Metaphysical Properties. It is polymorphous with the minerals Microcline and Sanidine.These three minerals form the Potassium Feldspar group.They are almost identical in physical properties, and it is sometimes impossible to distinguish one another without x-ray analysis. Most microline is formed at high temperatures during crystallization of magma or by deep metamorphism. Has perfect cleavage parallel to {001} and good cleavage on {010}. HISTORY, NAME, LOCALITIES: Microcline was recognized as a mineral species in 1830. Microcline is also helpful to our brains. Crystallography : Triclinic, a = 8.58, b = 12.96, c = 7.21, a = 89.7°, b = 115.97°, g = 90.87°, Z = 4; space group P1; point group 1. Common in plutonic felsic rocks, asgranites, granite pegmatites, syenites; in metamorphic rocks of the greenschistand amphibolite facies; in hydrothermal veins. The largest documented single crystals of microcline were found in Devils Hole Beryl Mine, Colorado, US and measured ~50x36x14 m. This could be one of the largest crystals of any material found so far.[1]. Microcline is a Feldspar. Calculated Properties of Microcline : Electron Density: Bulk Density (Electron Density)=2.54 gm/cc note: Specific Gravity of Microcline =2.56 gm/cc. Metaphysical Properties of Crystals & Healing Stones The definitive guide. The chemical compound name is potassium aluminium silicate, and it is known as E number reference E555.

COLLECTORS’ INFORMATION: Collectors value microcline for its rarity of well-formed and frequently twinned crystals. Like waters deep and ancient, Amazonite beckons in captivating shades of turquoise-green, promising to soothe the spirit and calm the soul. [2], In 2008, it (along with other Aluminum compounds) was the subject of Zircon supports those with altruistic ideals ground them into the energies of the everyday. This crystal helps us dream and helps us remember our dreams. METAPHYSICAL PROPERTIES, LORE, USES: Metaphysical practitioners believe that microcline stimulates clarity of thought, enhances general understanding, and improves one’s ability to cooperate with others.

Microcline feldspar - a mineral species with chemical composition of KAlSi2O8. Microcline typically contains minor amounts of sodium.
