A simple specimen, this piece contains about 10 very beautiful, well-developed Chalcopyrite crystals. These crystals take on the form of twinned disphenoids, and some look very similar to dodecahedrons. The largest of these crystals measures 0.4 x 0.3 x 0.3" (1.0 x 0.8 x 0.8 cm), and like the others, is in excellent condition and free from human-induced damage. All have the characteristic deep golden coloration and metallic luster of Chalcopyrite. All of these crystals are grown on to sphalerite crystals that rest on the quartz base. The sphalerites are small but well-formed, and in one instance seem to be compressed into a larger, "composite crystal". The quartz base on which they rests consists of a crust that is made up of scores of small transparent crystals with excellent form. This specimen has excellent contrast- it's very easy to see the Chalcpyrites against the white background, and as they are all slightly raised off of the quartz druse, they are easy to examine.
