High-Quality Indonesian Opal Petrified Wood Polished Slab (11137)

Indonesian opalized petrified wood, polished to a beautiful shine on one side with a late stage mineral coating on the opposite side. This material is found in limited deposits in hand-dug shafts, and is now becoming very difficult to find, and expensive. High quality pieces like this are now becoming mined-out, difficult to find, and expensive. We searched our inventory and are selling our last pieces of material that are ready to sell. We have several pieces that are not yet polished and will be offering those later this year.

Indonesian petrified wood formed when volcanic ash, mud and debris destroyed and buried trees and tree branches. Over millions of years, groundwater that is saturated with silica, copper and other elements seeped through the debris and into the wood, replacing the wood structure with brightly colored silica.
