A superb radial group of large, translucent, pale green paravauxite blades with a few sharp individual crystals protruding out the side. The blades produce a rounded sheaf-like roll almost forming a circle and resembling an ornamental snail! This graceful, competition quality thumbnail is likely a product of the efforts of Mark Bandy 70 years ago. It has a Jean Hamel collection label, and thee two did a lot of dealing together apparently, or she had a stash from him at some point. Paravauxite is a hydrated iron aluminum phosphate with hydroxyl. Complete all around with scattered tiny pockets of white clay. For a thumbnail, this is a well balanced and unusually fine specimen.
