This specimen has more than two dozen pink balls of xonotlite intergrown on its surface. A few of them have broken open, revealing the radial crystal growth and a white interior - only the outer surface has a pink color. There is also a druze of tiny colorless clear crystals, probably quartz, although the shapes are more like Herkimer diamonds than like common hexagonal quartz crystals.
