Kyanite Properties Facts and Photos

the mineral kyanite

Kyanite from Greek 'Kyanos'

Kyanite is a natural stone that's not particularly common.  Its name comes from the Greek word 'kyanos' meaning 'blue'.

Despite being brittle it's widely used in industry primarily because of its exceptional hardness.  It also has the ability to tolerate heat.  When heated kyanite expands and in some cases can double in size.

A translucent mineral with a vitreous lustre, kyanite is known for its zones of colour and variation in hardness.  Whilst most natural minerals have one hardness kyanite and a few others have two.

When tested lengthways it grades 4 to 5 on Mohs scale of mineral hardness.  When tested across the width of the same crystal it grades 6 to 7.  This characteristic along with crystals being brittle makes kyanite a difficult stone to cut.

Crystals tend to form as long narrow blades.  Being so fragile means kyanite is not ideal as a gemstone but is still used selectively.  Stones must be handled carefully because they damage easily.

When used as a gemstone crystals tend to be faceted.  It's not uncommon for them to have a 'scratchy' appearance and/or other minor surface marks.  The finest grade kyanite can rival the colour of blue sapphire.

When used for its metaphysical properties kyanite does not accumulate or retain negative energy.  A stone of tranquillity, it stimulates communication and psychic awareness.  It can also be used to align the chakras

Kyanite can help one to persevere in activities and situations that would normally reduce strength.  It balances yin and yang energies and clears energy blockages.

Kyanite can be found in the United States, Brazil, Switzerland, Russia, Serbia, India and Kenya.  Fine gem grade kyanite has also been found in Nepal although exact quantities are unknown.
