What is Kyanite?

Known for its exceptional metaphysical properties, Kyanite has always been an alluring gemstone since its evolution. Interestingly, it is a relatively new gemstone discovered by man. Its name deriving from a Greek term Kyanos denoting blue color, exhibits its lustrous beauty exuded by this color in particular. However, it is also found in several other amazing shades. This blue silicate mineral is extracted generally from metamorphic and sedimentary rocks having rich stores of aluminium. It has unique properties of variable hardness that changes with its direction. Like Tourmaline, Kyanite is also an effective magnetic stone relating to earth’s gravitational forces. As such, it was extensively used as compass by ancient travelers. It is also a rare gemstone that is free from negative energies and thus it does not require to be cleansed for wearing. Rather, it is used to cleanse other gems from their impurities. Its unlimited cosmic powers make it an excellent stone for meditation.

Kyanite Stone Properties

  • Kyanite is formed as a result of high pressures in minerals at the time of metamorphism in sedimentary rocks. It is most commonly present in gneiss and schists though it can also be found in quartz or eclogite.
  • In actual, it is a bladed crystal in which the hardness changes with its direction. Due to this reason, this long stone is also called Disthene meaning two strengths.
  • This stone can be used as a parameter to judge the factors leading to metamorphism of rocks like depth, temperature, or pressure at which this phenomenon occurs.
  • It has extensive industrial uses for heat resistant ceramic products, porcelain fixtures, abrasives, electrical insulators, spark plugs, mortars, grinding wheels, and electronics. Due to its perfect cleavage and wavering hardness, it is also quite aptly used for gem cutting.
  • The newest and rarest variety of Kyanite is its orange color which is generally extracted from Tanzania. This color is caused in this stone by presence of manganese in small quantity in it.
  • The chatoyancy of this semi precious stone is hindered by its cleavage and its varying hardness called as anisotropism.
  • It has uneven color variation where its color darkens towards interior of stone.
  • Kyanite basically stimulates throat and heart chakra in body but its chakra healing powers vary with its different types. Every color of Kyanite has impact over different chakra.
  • The transparent type of Kyanites are cut as cabochons and used for gemstone purposes.
