Dear Jim Bozeman,

Your student will have to cut a refractory crystal to do this. Quartz is =
no use since it will be subject to the usual phase changes which will =
destroy it. My suggestion is to get some faceted synthetic corundum, aka =
ruby and sapphire, which is aluminium oxide. Cannot guarantee it will =
hold its colour. If you need an contact for a cheap source of cut stone =
contact me off list.

All the best,
