This specimen consists primarily of yellowish bladed crystals of Siderite. Covering about half of the specimen are fine grained, small crystals of Muscovite of a light color with a high sparkly luster. There are several light green, semi gemmy, Apatite crystals and one larger crystal at the top of the specimen which is considerably darker in color. The largest Apatite crystal is 13 mm long and 16 x 11 mm in cross section. There are several bright silver colored Arsenopyrite crystals and a number of smaller ones including some of which are included in the Siderite just below the surface. The specimen has been glued onto an acrylic base. The specimen is in fairly good condition but there is damage to two of the corners of the largest Apatite crystal and some of the Siderite crystals have cleavage planes.
