Kyaniitti raakapala 4-7cm
The topics of blue kyanite are the completion of one's life's task as well as the strengthening of rational, logical thinking - in this way even confusing situations can be dealt with decisively.
The name disthene is derived from the Greek "this sthénos" (two-fold strength, two-fold strength). This describes a completely unusual behaviour of blue disthene: it has - depending on the direction in the crystal - two very different hardnesses (so-called hardness anisotropy).
Blue disthene is also named kyanite or cyanite.
