Some of the most aesthetic and displayable specimens of Wavellite have come from the Siglo XX mine in Bolivia as described by Mark Bandy. This piece does not disappoint with several fine, rare, creamy yellow color, sphere-shaped radiating aggregates measuring up to 8.5 mm associated with gem quality Quartz crystals on matrix. This is a nice display specimen of an uncommon mineral. The main Wavellite spheres are totally undamaged and very attractive. Ex. Brian Kosnar.
