This is a very rare necklace as it's made from 20 million year old petrified wood from Indonesia. I have placed it on a sterling silver chain with sterling silver lobster clasp. Please choose your necklace length or the default of 18" will be sent.
How was this formed?
Indonesia is a volcanic island chain that is currently active and this volcanic activity produces a wide array of unusual minerals and rocks. When wood is buried by volcanic ash and silica is mobilized from the ash, the silica will penetrate into the wood and replace the grains of the wood. Opal is a hydrated silica.
This is a one of a kind piece and a rare material.
