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.

Here are quite a few green balls of wavellite, most of which are only exposed along a broken face where the rock was separated from its neighbor. But a few of the crystals (and one in particular) show excellent spherical form and even classic surface terminations and texture. The crystal do vary in color, some dark green but most with a hint of yellow.
