This is a small nodule of native arsenic. It appears to be a cluster of intergrown rhobohedral crystals which have weathered to a dull black appearance, with rounded corners. It is accompanied by several tiny crystals of some colorless clear mineral which has weathered such that I cannot identify it, and also with a light dusting of a cream-yellow mineral, undoubtedly some kind of arsenate. The arsenic is clearly crystalline in form, and the specimen is undamaged.
