"Porcelain Whiteskin" Tree Fern Slab - 5.6"
This is is a gem grade specimen of Permian aged petrified wood from the tree fern, Tietea. It has a beautiful white "skin" to it which is so well agatized that it's just like porcelain. The unique coloration is of these slabs are the first I've seen in tree ferns from Brazil. An absolutely beautiful specimen.
