This specimen is a mound of calcite crystals with a partial brownish oxide coating and sporting many, many donnayite crystals. The donnayite crystals are, mostly, hemimorphic smaller crystals with the exception of one larger, yellowish, doubly terminated, pseudohexagonal prism. Very good for this mineral! Type locality!
