NM61D9: Let’s see: some scalenohedrons of Calcite once existed in the pocket. They are now long gone and all that remains is the form of the faces of the old Calcite crystals that have been preserved by the coating of Quartz that formed on them. It is a floater with a very clean appearance and great originality. It is the most spectacular of the specimens of this type that came out of this find.
The specimen has been reviewed and published in the magazine ‘Bocamina’ on page 62 in number 19, year 2007.
