Kyanite

KYANITE
** Kyanite is a very unusual stone in that it has two hardnesses on Moh's Scale, depending on the direction it is tested. It grows in crystals shaped like long, flat blades, and it cleaves along perfect lines. Whereas other minerals have the same hardness all around, Kyanite shows a hardness of 4-5 when tested lengthwise, and 6-7 (harder) when tested crosswise.** While Kyanite is typically a blue color, it sometimes comes in green, white, and yellow. It exhibits strong pleochroism, which means it looks different colors when viewed from different angles. Its color can look dark blue from one angle, and white or colorless from another.** The word "Kyanite" comes from the Greek kyanos, which means "blue," in reference to its color. This mineral is also known as Disthene, which comes from the Greek di, meaning "two," and stenos, meaning "hardness," a name given because it has two hardnesses.** Metaphysical healers use Kyanite as a claming stone. It helps to focus the mind and dissolve mental and emotional confusion. It helps the wearer let go of his or her anxiety. It keeps the mind focused and able to ward off distractions.** Kyanite is thought to be a highly creative stone, enabling the wearer to tap into his or her creative talent in art, music, dance, writing, and other artistic expressions.** Gem-quality Kyanite is extremely rare. Its perfect lines of cleavage and its brittle, splintery nature make it very difficult to cut, and stones of fine color and transparency are rare.** Commercially, Kyanite is used in the manufacture of spark plugs and heat resistant ceramics
