Excellent smoky quartz pair with hyalite Agate The calcite has also formed

The calcite has also formed stacks of small scalenohedral crystals

and actually share the same crystal lattice

These pieces can be fascinating to study up-close

The large hexagonal formation is characteristic of pyrrhotite
