12.3" Graveyard Point Plume Agate Slab - Eastern Oregon

This is a gorgeous, large slab of graveyard point plume agate from the Owyhee Mountains in far Eastern Oregon. It is polished to a glossy finish on one side and is cut flat on the other.

This specimen comes with a display stand.

Long known for its beautiful "plume" inclusions that look like moss or snow-covered trees, agate from this area comes from just a couple of small mines. Plumes or dendrites that occur within rock are most often a result of intruding (percolating) mineral solutions that contained manganese and/or iron. These solutions can work their way through microscopic cracks in the rock, leaving behind a branching pattern throughout the agate. By an untrained eye, these can be mistaken for plant fossils within the rock.
