Petrified Wood RARE Polished Round Slab California #OCa2
Lovely Petrified Wood from California that has been slabbed, and polished on one face.
This is a complete round with "bark" all the way around and it is 5.87 inches by 3.72 inches and .73 of an inch thick.
This piece is from the Kirkby collection and was self-collected sometime in the 1930's to the 1960's.
It has "Calif" written on the back-but unfortunately I do not know where in California.
Petrified Wood formed when a tree died and was buried by sediments. Minerals in the groundwater then permeated the wood, replacing the original organic matter and turning it to stone. The main mineral is silica, but trace elements in the silica create a variety of colors.
