Erythrite

Erythrite from Mount Cobalt mine, Mt Isa QLD

    0%

    Erythrite is a bright red-purple colour cobalt arsenic, oxygen and hydrogen mineral. This colourful characteristic makes it very noticeable and easy to identify. This specimen was mined from Mount Cobalt mine, Mt Isa QLD Australia.

    Unfortunately this specimen is slightly damaged with a crack in the middle but is still in-tact on the matrix. I am looking to acquire a new specimen that has nice transparent crystals.

    I acquired this specimen from Greg from Blue Gems at the August 2016 Sydney Crystal Show.

    Did you know!?
    Many miners refer to Erythrite as “Cobalt Bloom”. Larger size crystals are quite uncommon and not necessarily that amazing.
