Rodney, the Charoite is bad even in the pliable Tru-stone I did a regular Charoite on an American with some I had from when we used to make jewelry, I have a bunch of the old original stuff, I had a customer that was too cheap to use real stone. I cheated, I used my metal lathe and carbide tooling, I want to try the new pliable Tru-stone it's supposed to be pretty decent in most materials, with the Charoite and Lapis being the hardest, you did a fine job on that pen.
