A +41 crystal with a level 10 requirement is cosmetic to you? Crystals with that kind of stats created by an artificer require level 50. For level 10 (well, level 7 really) an artificer can create a crystal with a measly +2 bonus.
I've had a 400 artifice since March and color crystals have never been a great profit making activity for me.
On the flip side, I've made a ton of money on hilts, enhancements and relics.
