One of the more attractive that I have seen, this native Sulfur specimen consists of a large chunk of calcareous shale host rock in which a deep cavity extends. This cavity is lined with dozens of trigonal pyramidal calcite crystals, and is the resting place of at least 6 large orthorombic prismatic Sulfur crystals. They are in excellent condition, as the depth of the cavity has protected them from damage. The largest crystal is not quite complete due to the tightness of the hollow's space, but has visible dimensions of approximately 1.5 x 1.0 x 0.6" (3.8 x 2.5 x 1.5 cm). All have good form, with well-defined edges and clean, smooth face that show a bright, pearly-to-vitreous luster. They have the standard bright-yellow coloration of native Sulfur and are translucent, showing small areas of moderate transparence. The calcite crystals that line the hollow are generally in excellent condition and have the trigonal "dogtooth" form that is common for this mineral. They have a pale cream coloration and a pearly luster, and are dimly transparent.
