Chemical Formula: Al3(PO4)2(OH,F)3.5(H2O)

Chemical Name: Hydrated Aluminium Phosphate Hydroxide

Mineral Class: Phosphate

Mineral Notes: Wavellite is a mineral that demonstrates the classic botryoidal crystal habit. It produces a unique effect when the globules are imbedded in rock and then fractured. The result is a radial cluster which reflects light to produce a sparkling pinwheel effect. 

Description: An outstanding specimen of pale-green Wavellite upon a matrix of grey sandstone. Crystals of the mineral are arranged in pin-wheel clusters. Individual crystals are easily seen. These have a very stong luster and a very attractive colour.

Location: Avant Mine, Garland Co., Arkansas, USA.
