I. The Metaphysical Reading

How the stone has been held.

Creedite is worked with as a stone of joyful clarity, kept nearby during ceremony, teaching and any moment when a private insight is asked to become a shared one. Practitioners hold it as a reminder that some understandings arrive all at once.

II. The Scientific Reading

What the lattice actually does.

Creedite is a rare hydrated calcium aluminium sulfate-fluoride first described from the Creede District of Colorado in 1916. Its most spectacular specimens come from the Navidad mine near Rodeo, Durango, where bright orange radiating sprays grow on brown limonite matrix. It is soft and cleavable and should be handled with care.
