The rare wurtzite (beta-ZnS) is found in Tanzania as a brown to strong red crystal and crystallizes in the hexagonal crystal system. Zinc blende (alpha-ZnS) or sphalerite, on the other hand, crystallizes cubically. In fact, the two minerals are hardly clearly distinguishable visually and require more complex analysis methods. In Tanzania, both are called sphalerite.
