Dozens of heavily-intergrown Tetrahedrites help to make up this hand specimen. These crystals are in moderately good condition, as several are lightly damaged and a few are broken, and measure up to 0.5" (1.3 cm) along an edge. They have excellent tetragonal form and show the classic dark silvery-gray color and metallic luster of the specie. They are accompanied by several clusters of well-formed quartz crystals and rest on a sphalerite base that shows some surprisingly good crystal form of its own.
