Product Description
Petrified Wood Stone Slab La Salle, Colorado
Lovely unpolished slab of Petrified Wood that is 3.78 inches by 3.4 inches and 8 mm thick.
It weighs .28 lbs. and is shown wet in the first 2 pictures.
This pretty piece was in an old collection, it was most likely self collected in the 50's or 60's and it has "Petrified Wood-Lasalle, Colo" written on pencil on the back.
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.
