Desert Ironwood is a fairly uncommon tree, even here in the Sonoran Desert. It only grows here in Arizona, Northern Mexico, and a small corner of South East California. As uncommon as it is burls from it are even more uncommon. Pen blanks can run up to $20 each. Most of what I got was thin stock, suitable for pendants and inlays. I spent a couple hours today cutting up the smaller stuff along with some other stuff I've been holding onto for pendants.
