Siderite – big crystals

Poland, exact location unknown

Siderite – big crystals
SOLD *Prices include VAT
Article code:  V.B.0240.012
A truly impressive piece. A siderite specimen weighing more than 1 kg with very large, razor-sharp, brown-black crystals up to 3 cm in size.
The previous owner indicated that the piece came from Poland - but I have my doubts about that.
Perhaps you recognize the piece. If so, more information of the exact location is more than welcome. Please contact me.
Measures; 140x120x90mm. Weighs approximately 1,140 kilogramme.

Siderite, also called chalybite, iron carbonate (FeCO3), a widespread mineral that is an ore of iron.
