- Miniature, 3.4 x 2.0 x 1.1 cm
- Avant Mine, Avant, Garland Co., Arkansas, USA
This superb toenail specimen of wavellite from the premier finds in Arkansas shows very plainly the internal structure of massed acicular crystals that grow radially out from the center. This is actually a "ball inside a ball" - you can see the thin "shell" of the original ball that was later enclosed. This split ball sits up perfectly on a natural base of matrix with a layer of wavellite on it. Ex. Feist Collection.
