This specimen has almost no matrix to speak of; most of its mass is made up of Stibnite crystals that appear to be somewhat weathered. Although there are dozens of crystals on the specimen, very few terminations are visible. This is because their points of origin all occur on the outside of the specimen, with the crystals radiating inwards. The crystals have a uniform gray color, dull metallic luster, and occur in the form of long needlelike prisms with slanted terminations. The small amount of host rock appears to be a limestone or possibly a quartzite. This specimen has similarities to the STI-2 specimen from the same locality.
