Hauerite
is a simple Manganese Sulfide that is a fairly rare
mineral sought by by mineral collectors for its beautiful
reddish black octahedral crystals. There are very few
Hauerite mineral specimens available on the market,
most are from old classic European collections, but
faceted gems are almost impossible to find. It is rarely
faceted since it is usually black to reddish black,
opaque and does not have a very high polish. But, since there are Black
Gem collectors out there, I am including it.
The
main sources of Hauerite are Ronneburg Uranium deposit, Gera, Thuringia, Germany;
Destricella mine, Raddusa, Catania Province, Sicily,
Italy; Olkusz Mine, Olkusz District, Malopolskie,
Poland and Jeziórko Mine, Tarnobrzeg, Podkarpackie, Poland. Hauerite is also
found in the USA at
the Gulf and Big Hill salt domes, Matagorda County;
the High Island salt dome, Galveston County; the Boling
salt dome, Wharton County; and the Fannett salt dome,
Jefferson County, Texas.
