Calcite - Masua, Iglesias, Sardinia, Italy
 
 The 7.4 cm tall calcite, terminated as a scalenohedron twin, stands very representative on a matrix which is overgrown with other calcites. While the smaller calcites are milky and opaque, the large crystal convinces with translucency, good luster and a minimally yellowish color. An extremely aesthetic piece of the best quality from the Masua mine near Iglesias in Sardinia. A place of discovery right on the Mediterranean Sea surrounded by beautiful nature.
