This is a triangle shaped silver and black semi precious gemstone Crown of Silver Psilomelane designer cabochon 35 mm long by 29 mm wide and 3 mm thick.
A very rare semi precious gemstone-very hard to get-and very messy to cut!
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.
