One of the most interesting specimens that I have come across, this piece's mass is made up mostly of orthorombic Enargite crystals with pedion terminations that rest on a small section of quartzite host rock. Though several of the crystals show considerable and sometimes severe damage, the piece is in generally good condition. The largest of these crystals is quite impressive, with dimensions of 0.5 x 0.4 x 0.4" (1.3 x 1.0 x 1.0 cm), and is in excellent condition. Broken surfaces show their gray-black color, nearly adamantine submetallic luster, and complete opacity. Nearly all of the intact surfaces, however, are covered with a thin layer of what appears to be bornite or a closely-related sulfide. The coating has a more metallic luster than that of the Enargite, and is awash with wonderful golden and red-violet colors. The visible surfaces of the quartzite base on which they rest is at least 50% covered with tiny transparent quartz crystals. It is a very beautiful specimen of an uncommon mineral.
