Well crystallized forms are referred to as destinezite, which has been given official recognition by the International Mineralogical Association with diadochite being the poorly formed to amorphous variety. It has a greenish yellow to brown colour and forms nodules or crusts. Its appearance has been compared to cauliflower.
