STATE MINERAL/GEM Talc, the State Mineral, is metamorphic in origin, formed in thin slivers of ocean crust left here after the continents collided. Generally found in southwestern Vermont, it is green in color and very soft. In 1990, Vermont ranked second only to California among the states which produce talc. Ground talc is used in plastics, paper, rubber and paint. Grossular garnet, the State Gem, is technically a mineral -- a silicate, which is colored brown due to the presence of iron. Grossular garnet from the Belvidere Mine at Eden Mills is thought to be the finest specimen of its kind anywhere. ------- from Office of the Secretary of State, Vermont Legislative Directory and State Manual, Biennial Session, 1993-1994, p. 25.
