Being a wargamer I instantly spotted the potential here. I thought this would be something cool for put narrative Konflikt 47 campaign. Surely Professor Lange would be interested in this strange crystal.
I decided it would be cool if I could get them to glow as well so I ordered some tea lights.
Once they arrived I set to making them.
Glued the lights down to CD bases (not worried about changing the batteries as my smoke lights are still going and they are a good few years old). Next up was filler all over the base to build up a little rock pile. I then added crystals all over the pile around the tea light.
A layer of black undercoat, then a few layers of grey to build up the rocks.
Then I added flock and here they are
Quick and dirty but does the job I believe!
