10.2" Graveyard Plume Agate Slab - Eastern Oregon

This is a gorgeous specimen of Graveyard 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 an acrylic 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. To an untrained eye, these can be mistaken for plant fossils within the rock.
