Calcite & Quartz (Cumberland habit)
Sa Ducessa Mine, Oridda, Carbonia-Iglesias Prov.
5 x 3.7 x 3 CM (miniature)
pre Tucson 2015 update
An odd yet attractive very old Sardinian Calcite specimen with a second generation of Quartz in "Cumberland habit". The Quartz also has numerous inclusions and some is in stacked groupings. There is considerable Hematite on and in many crystals here, adding nice color contrast. In good condition and attractive, most everything is doubly terminated.
