I have used dinosaur bone (agatized), petrified wood, jadeite and nephrite jade, crysanthemum stone, and other neat stuff for Colt 1911 grips. I use standard lapidary equipment as it is all harder than steel. Sometimes there are pits or porosity in some of the stones so I use Paleo Bond to fill them then grind as normal.
The dino bone shows cellular structure and looks much like forged cable steel. I used white/black dino bone to match a blade I had and it was WAY COOL.
