This is Psilomelane-also known as Crown of Silver Psilomelane from the Silver Crown Mine in Chihuahua, Mexico.
This wonderful gemstone cabochon material (pronounced si-lah'-mi-lane) is a type of manganese ore. The designer cabochons are shiny metallic black with silver banding and swirls, hence the name.
