This stone comes from Western Australia.
A petrified wood, dark in colour with light patches resembling peanuts.
Before the wood was petrified it was washed into the sea as driftwood.
It was then attacked by wood borers before sinking to the ocean floor.
The borer holes then filled with sediment of microscopic sea creatures and silicate took on the form of the timber.
As the ancient seas retreated the peanut wood was revealed.
This process is believed to have occurred 120 million years ago.
This pendant measures 4.5 cm in length x 4 cm at its widest.
