Description
Apophyllite, a Zeolite, is Silicate mineral with very well-defined clear Crystals and is very popular as a collector’s mineral. The Crystal structure will refract like in obvious rainbows and can form “natural pyramids” when tumbled.
Mordenite is orthorhombic. It crystallizes in the form of fibrous aggregates, masses, and vertically striated prismatic crystals. It may be colorless, white, or faintly yellow or pink.
