Mordenite is a hydrated mineral of sodium, calcium, and potassium aluminosilicate. It is a member of the zeolite family. Its most common colors are chalk-white and salmon-orange pink. Other unknown species include yellow, red, and colorless. It was discovered in 1864 by Henry Howe. He chose the name of a small town called Morden in Nova Scotia, Canada.
Mordenite crystallizes in the form of masses, striped needle-like points, fibrous aggregates, and small prismatic shards. Crystal healers believe that Mordenite greatly protects the heart and also helps to support deep emotional relationships through love. Mordenite has been found in Russia, India, Iceland, Italy, Scotland, and the USA.
