Triangle shaped semi precious gemstone Crown of Silver Psilomelane designer cabochon 37.5 mm long by 25 mm at its widest by 4.5 mm thick.
It does have a slight flat spot and what I call a "B" design on top!
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.
