Scapolite, is a common, opaque gem that is usually yellow or purple. It is popular for its strong fluorescence and its Cat's Eye effect which is highly desirable. It scratches easily so it isn't commonly used in jewelry in spite of its beauty.
Gemstone forms of Scapolite come from Tanzania, Madagascar, Afghanistan, Tajikistan, India, China, Burma (Myanmar), Brazil, and Canada. Scapolite gemstones are generally natural and not enhanced, though it may be possible for certain forms to turn pink upon heat treatment.
