Blue kyanite

ETYMOLOGY: Kyanos comes from the Greek, meaning 'blue'.

CRYSTAL SYSTEM: Triclinic.

PRINCIPLE OF FORMATION: Tertiary.

MINERAL CLASS: Nesosilicatos.

MINERAL ELEMENTS CHEMICAL FORMULA: Al 2 O [SiO4].

HARDENESS: longitudinal 4 to 4.5 transverse 6 - 7 In the Mohs scale.

FIELDS: Brazil, Russia, India, Zimbabwe, Madagascar, United States, Switzerland.

MINERALOGY:  An aluminum silicate, polymorphic is characterized by varying hardness, it is much more cross-hard longitudinally, therefore also known as kyanite, is one of the peculiarities of this material, which makes it extremely difficult to cut. They are widely distributed but limited way in metamorphic rocks in storm deposits, has elongated tabular crystals. His intense blue color is due to electron transfer between adjacent metal ions Fe2 + to Fe3 + and Fe2 + to Ti4 +, this phenomenon is known as Intervalence Charge Transfer (IVCT).

MYTHOLOGY: The kyanite is sensitive to both heat and shock, so you should avoid using steam and ultrasonic cleaning products and assemblies must be protective. Legend indicates that in northern Europe, near the Mediterranean Sea natural disasters occurred: A huge storm that broke the biggest seas in Europe, prompting the destruction of the rich mines in quartz and sapphire. This caused the destruction of such ores, happened, sea salts combined with sapphires and quartz, making them his white and colorless led stripe in the center and fathered was how this new and beautiful mineral called today "Kyanite".
