Mineral Specimen #4475 Hydroxyapophyllite-(K) on Prehnite
Fairfax Quarry, Centreville, Culpeper Basin, Fairfax Co., Virginia
Ex. Robert Gannon
Well formed cubic crystals of clear to white colored Hydroxyapophyllite on green colored botryoidal Prehnite. Some of the Apophyllite crystals have phantoms. The green color of the Prehnite is richer and better than often seen from specimens from the location.
Flaws: Nothing Appreciable
