Wavellite is a mineral that demonstrates the classic radiating globule crystal habit. In fact, you could say that wavellite is the type mineral for this habit. The habit produces a unique effect when the globules are imbedded in limestone and chert. If the rock is fractured and some of the globules are cleaved through, then a nice radial cluster is seen. The radial cluster will then reflect light to produce a sparkling pinwheel effect. Although broken mineral specimens are generally not valued by collectors, the radial play of light can be rather pretty and makes for interesting specimens. Although, a serious collector might not admit it, the more valuable specimens are those that are predominantly pristine, uncleaved clusters with at least a few cleaved globules to demonstrate the light play.
