Continuing Sam's investigations on crystal shapes and materials, and 
using KrystalShaper as the primary crystal builder.

This is a crystal of apophyllite. The coloured variety is 
Fluorapophyllite-(K).

I based the material on the one given by Sam in the "Alum" post in 
September last, including Alain's comments. I then added surface normals 
from the crystal experiments by Jaime Vives Piqueres, as also a more 
'cloudy' aspect using a bit of scattering media, and a density block. 
Finally, I added photons. Possibly, the hue should be a tiny bit more 
bluish-green...

The environment makes use of a hdri map and a spotlight. The render 
makes use of a, non-optimal, stochastic setting, which explains the 
grainy aspect. However, I am still experimenting.
