The polished balls of blue disthene have a diameter of 8mm; the total length of the strand is about 40cm.
Analytical stone medicine appreciates the effect of disthene in situations where it is necessary to keep a cool head and keep track of things.
Blue disthene is also known as kyanite or cyanite. The name disthene is derived from the Greek "this sthénos" (twofold strength, twofold power). This describes a quite unusual property of disthene: It shows - depending on the direction in the crystal - two very strongly deviating hardnesses (so-called hardness anisotropy). Spellings such as Distin, Disthin or Disten have not become established in the retail and wholesale trade.
