This is a good specimen of powellite. The crystal is incomplete, showing only three faces. The remaining surfaces appear to be growth patterns or possibly contact imprints, except for an area of damage on the bottom. There is a very nice (unfortunately incomplete) arrowhead face on one side, which suggests that the complete crystal would have had a similar shape. The crystal faces show distinct striations. The powellite is transparent and pale yellow, with many internal fractures. And of course this powellite fluoresces a bright yellow under UV (very bright with long wave).
