Both have good luster.
Almost a mineral collection in one specimen. A light green pseudo-cubic crystal of Fluorapophyllite sits on top, but there are also nice crystals of Stilbite, Scoleciteand Calcite
Some call these specimens Calcite, some Aragonite.
Because of the well formed white scalenohedral crystals, I look at them as Calcite. It is much nicer a that I could get the photo to show.
Oriented fans of fibrous Malachite with very good color and luster make this a very a very nice display specimen.
The arch of well formed Stilbite crystals make this a very aesthetic specimen.
Attractively displayed sharp black crystals with excellent luster. The largest one is 3 cm.
