A material formed by the silicification of wood, generally in the form of opal or chalcedony, in such a manner as to preserve the original form and structure of the wood. Also known as agatized wood; opalized wood; petrified wood; woodstone. Petrified wood has been preserved for millions of years by the process of petrification. This process turns the wood into quartz crystal which is very brittle and shatters. #petrifiedwoodstone #artfoss#senibatualam (at Banten, Jawa Barat, Indonesia)
