Petrified Wood Thick Stone Slab Unpolished Rough Rock
This unpolished thick stone slab of Petrified Wood is 5 inches by 3.9 inches and .8 of an inch thick.
It weighs 1 lbs. and is shown wet in the second and third pictures.
Lovely petrified wood from Washington.
This pretty piece was in an old collection; it was most likely self-collected in the 50's or 60's. It was coated on one side with some type of glue that has yellowed (first and second picture).
This gemstone is the fossilized wood of trees. The 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.
