I did a piece of sculpture once in coco bolo. Must say it is a beautiful wood and I liked working it. Years later I heard that the dust is toxic. I generated some dust in the sanding of it, but experienced no problems. Does anyone have more information about this? In reference to ejames' question, you don't stain that wood. It is too dense and waxy, but the color is such that you wouldn't anyway. It is a gorgeous purple when you work it and oxidizes to a beautiful dark gold brown.
