Baryte 6kg (France) on black base
PUMI1921
A perfect slender block of Baryte crystals with so-called "whistle" crystals. They come from the Maine mine (Saône et Loire in france), a fluorine mine closed in the late 1970s. Very large geodes of more than 10 m2 were discovered at minus 120m deep underground. They were entirely lined with crystals, and miners were able to enter completely in them.
