Creedite is a calcium aluminium sulfate fluoro hydroxide mineral range from clear crystals to purple and orange. It can form very small and fine crystals to decently large specimens. It is one of the eye grabbing minerals in my opinion. This piece though hard to tell with the camera contains orange,white,and black crystals. It lands around a 3.5-4 on the Mohs scale of hardness making this mineral quite fragile.
