Kyanite from Minas Gerais, Brazil

    0%

    Kyanite, a aluminium silicate mineral often found in groups of light-blue crystals. This beautiful specimen was mined in Minas Gerais, Brazil. A similar variety is also found in Harts Ranges, NT, Australia. It would be a dream to be able to visit the Northern Territory to go fossicking for Australian Kyanite and have it displayed in my collection.

    I recently acquired a a few small pieces of Australian Ocean Kyanite from Patrick Gundersen who hand collected it from Harts Range, it will be listed soon.

    I acquired this specimen from Tony at Mineral Store at the August 2016 Sydney Crystal Show.
