Apophyllite, Hydrated Potassium Calcium Sodium Silicate Fluoride Hydroxide, is a glassy, cube-like crystal appearing white or clear, faint pink, or (more rarely) faint green in color. Its name comes from the Greek, "to leaf apart," because the crystals tend to peel or flake apart when they are heated due to the loss of water molecules. It is often found with samples of other silicates such as stilbite, heulandite, and prehnite. Apophyllite is too soft and brittle to be used as a gemstone.
Apophyllite allows you to recognize and act upon the truth in all situations, stimulating the intuition. It has been used as an assist in astral travel and to help recall information learned during travel. Those interested in the future may find apophyllite useful as a gazing stone.
