The Mineral Kyanite

The mineral Kyanite, generally seen in metamorphic pegmatites that are Aluminum- rich or in sedimentary rocks, is a silicate mineral of a specific blue color.

Kyanite is associated with the aluminosilicate sequence, the Alusite and polymorph series and also the polymorph Sillimanite. The Kyanite mineral is very much anisotropic, so much so that its hardness differs based on the direction of its crystallography. This anisotropism in Kaynite is perhaps an identifying characteristic.

Kaynite is a mineral of aluminum silicate, frequently found as crystals of a long thread like blades, which are either translucent or transparent with a pear-like sheen. The frequently occurring colors used in metaphysics are indigo, black, white and green. At times they are found in colors of pink, gray, yellow and most recently they are found in orange color.

The other places where Jamesonite was obtained are Arkansas, Southern Dakota, USA; Mexico, Zacatecas and Rumania. Jamesonite is not a mineral that occurs commonly.

Jamesonite represents one of the rare minerals of sulfide found in the form of delicate acicular crystals, with the appearance of fibers in the form of hairs that are thick enough to envelope the crystal with their fibrous hairs. If not, it becomes sparingly dispersed among other minerals and mistaken for the real hairs.

Occurrence
Kyanite is found in pegmatite, gneiss, quartz and schist veins as a result of the high pressure metamorphism pertaining mainly to pelitic rocks, in sedimentary rocks, it occurs as detrital grains, in association with Staurolite,  Dalusite, Talc, Sillimanite, Gedrite, Hornblende, Corundum and Mullite.

Derivation of Name
The NAME Kyanite is a derivation of the Greek word kuanos, at times having reference with “kyanos”, which means bark blue

Chemical Formulae
Al2SiO5

Physical characteristics

  • Color – The different colors in which Kyanite occurs are gray, blue and very occasionally in pink, white, Blue, orange,  black, and green
  • Transparency – Translucent to Transparent.
  • Luster – Pearl-like to Vitreous.
  • Fracture – Splint-like
  • Associated minerals

Hardness
6.5-7 perpendicular to that axis

Density

3.56 - 3.67, Average = 3.61

Applications
The principle use of Kyanite is for ceramic, refractory and plumbing fixtures in porcelain and dishware.. Besides, it is of use as in abrasives, as electrical insulators and in the field of electronics.

The mineral Kyanite’s importance as an index mineral for estimating the depth, temperature and pressure by which metamorphism takes place in a rock can never be underestimated

Mythical Uses
When one is at some work, possessing a Kyanite, either wearing it, or holding it, enhances your communication develops a better way of expressing yourself and speaking the truth, it sets right the differences in ideas and beliefs.

For those who are frustrated or those who are tempted in interrupting a deed of destroying themselves, a Kyanite stone acts as a network that empowers them to back track. Kyanite helps you to memorize the past childhood or to recollect a name or word which evades you by just touching the mineral Kyanite in the middle of your forehead.

The black colored Kyanite along with its basic power, sustains curing of the environment, and helps to remove pollution from the earth, leading to the earth’s development.
A sufferer who is mentally incurable is helped by Kyanite to overcome the situation

Gemology
Rarely do we come across the Kyanite that possesses clarity and color. Such Kyanites are very expensively priced by the gemstone cutters. It is likely for an uncut precious stone to be cut into facets; otherwise they make use of it in making pendants and beads. Since Kyanite is rarely used in jewelry, it is referred to as an “exotic” gem stone.

Earlier Kyanite was used in the form of a partially precious gemstone, which probably displays cat’s eye chatoyancy, even though it has limited use in its clear cleavage and anisotropism.
