Psilomelane: Buy Loose Psilomelane at Affordable Prices from GemSelect

Psilomelane is an umbrella term for hard black manganese oxide and is composed of hydrous manganese oxide with variable amounts of barium and potassium. The name, psilomelane comes from the Greek for "psilos" (smooth) and "melas" (black) because of its smooth, black appearance. Psilomelane is often layered with gray pyrolusite, giving it attractive gray bands and swirls. It is often traded as "Merlinite" or erroneously called "black hematite", though hematite is iron oxide. Psilomelane often forms with barite, quartz, hematite and jasper. When intergrown with jasper it is traded as "psilomelane jasper".

I love your selection of gems. My only complaing is I wish I could put in a page number to return to that page.When there are over 60 pages of gems it is hard to return to a page with a gem I am considering.

I placed order#384714 based on the picture on your website and the stone came in much darker. I'm sure it's the same stone i ordered but your lighting made it seem a lighter blue. I was trying to match a stone for a customer and based on the picture it would have been close enough but the stone in person is a mile off.
