Creedite is a rare calcium aluminum sulfate fluoro hydroxide mineral known for its stunning appearance and unique properties. Here's a glimpse into its remarkable world:

Creedite Appearance:

  • Color: Ranges from colorless to white, violet, purple, and even orange.
  • Transparency: Translucent to opaque.
  • Crystal habit: Forms acicular radiating sprays of fine prisms, often resembling delicate needles or hair.
  • Cleavage: Perfect on one plane, making it easily cleavable.
  • Fracture: Conchoidal.
  • Luster: Glassy to pearly.


Forms in hydrothermal mineral deposits, often associated with fluorite.

Occurs as a secondary mineral resulting from the oxidation of fluorite ore bodies.
