Sodalite Slabs
Sodalite is often used as a substitute for
lapis lazuli, but it is a beautiful stone in its own right. The Moh's hardness
is 5-1/2 to 6 and it cuts easily. Polishes with cerium, aluminum
or tin oxide. Hackmanite (a variety of sodalite) is sometimes present in this material and is a slight pinkish or rosy color.
