Actinolite is a mineral that can be green, green-black, gray-green, or black in color and is made of crystals. It is common around the world. The environment it lives in is in metamorphic rocks. It is named after the Greek word aktinos (meaning "ray") because of the nature of Actinolite. Actinole is not radioactive.
