Crystal Attributes: Blue Kyanite


Basic Info

Kyanite is an aluminium silicate mineral that comes in several colours, although it’s named in Greek for its brilliant blue variety. It’s famous for falling anywhere between 4.5 and 7 on the Mohs hardness scale depending on the angle it’s tested at, and is usually either somewhat pearlescent or clear in colour. Often, Kyanite crystals contain more than one colour alongside each other, and you’re likely to find dark streaks running through the striations. Many believe it has intense healing powers as a result of yielding ‘high vibrations’, and is also a beautiful stone for cutting and setting in jewellery.


Kyanite is found in many countries across the world but is especially plentiful in Switzerland where it’s mined in Pizzo Forno, Ticino and occurs alongside staurolite. Great quality crystals are also known to be found in Vitória da Conquista, Brazil, and Borisovskie Sopki, Plast, and Chelyabinsk Oblast in Russia. In Kenya and Tanzania, you’ll find large stones in a deep teal as well as the rarer orange, which was only discovered relatively recently- in ancient mineral terms. In America too there are several locations where this stone is mined, which makes it fairly easy to come by and comparatively inexpensive if you’re looking to add a piece to your collection.


It was named in 1789 by Abraham Gottlieb Werner for the Greek cyanos or kuanos meaning blue, since it’s by far the most common colour to find or be used. It actually has plenty of commercial uses, and you’ll find it in ceramics, electronics and as an abrasive where its heat resistance makes it a great industrial material. Of course, it’s such a beautiful stone with such striking coloring that it’s often used as a gem in jewellery, and with its relative clarity can be cut for brilliance. In alternative healing circles, its purported high vibration index
makes it a perfect stone to cleanse the chakras with, and along with Citrine stones is not considered to store either negative or positive energy.


While blue is the most common colour, orange stones found in Tanzania seem to be a result of higher manganese content. More often though you’ll find Kyanite in indigo, green, white and black shades and while it used to be considered an exotic gem it is classified now as a semi-precious stone. The crystals typically come in long, thin slivers and splinter when they break, and if you’re buying them commercially or for a collection you’re likely to find it in a blade shape. They don’t usually take on a natural gloss but can be treated with oil to create more of a shine- which is something you might want to ask about if you’re buying if it’s not disclosed upfront. It’s fairly easy to identify because of its colour and its anisotropic qualities- that is, taken from different angles, it can measure anywhere between a 4.5 and a 7 on the Mohs scale.

Beautiful and fairly obtainable, Blue Kyanite is a versatile and sought after stone with plenty of practical and ornamental applications.
