TPM76AO0: Calcite replaced by sand

Group of crystals, with one of them clearly dominant and all of them doubly terminated, totally occupied by inclusions of sand. They are formed by a prism with curved edges and a poorly defined terminal rhombohedron. An American classic which it is currently very difficult to obtain in good specimens as the area in which they were found has been declared a National Park.

TX97AH3: Calcite with Aragonite

You can opine, perhaps, that Calcite is a “modest” species, but it can also reach unexpected heights of elegance as in the case of this complete crystal that is clear, colorless, very rich in faces and has additional elongated Calcite and Aragonite crystals with curious parallel growths. Due to its special transparency, the Calcite crystal has a high birrefringence that allows one to see “double” images through it.

JFD84AO0: Calcite with Baryte and Pyrite

Very interesting specimen for this mine because the very aesthetic Calcite crystals sit on large Baryte crystals coated by what look like orange iron oxides and are accompanied by small Pyrite crystals. Baryte is not a common mineral in El Hammam, I have rarely seen it there, much less in large crystals as in this case. As sometimes happens, I didn't buy it in Morocco but in Tucson 2009, from the Moroccan Ahmed Es Seouani.
