Linwood Mine Calcite with Blue Marcasite and Black Dolamite

Linwood Mine Calcite with Blue Marcasite/Pyrite and Black Dolamite From Linwood Mining Company in Buffalo, Iowa, Scott County. For quite a while the Mining Company has not allowed employees to remove Calcite pieces from the mine. You can only get pieces from the second market or if you are lucky enough to purchase a piece from a former employee. I live about 5 minutes from this beautiful mine located along the Mississippi River. Measures approximately 3.3 X 2.3 inches. This piece is very sparkly with amazing Blue Marcasite/Pyrite patches. The matrix is Limestone. From my no pet, non-smoking home.
