Found my plaster, I am going to whip up a few casts here soon.
Now, has anyone seen any good tutorials for making giant crystals, I considered buying a bunch of real Quartz crystals, but it appears to be far too expensive. Same with Armorcast (though they look great) I am currently thinking about taking a chunk of insulation board, then sanding it down to make a hex shape, then cut the top down and paint like you paint gemstones, darker on top lighter at bottom, with a sharp highlight at the top.
