Peanutwood/Peanut Wood Jewelry

A very fascinating material, it is a sedimentary gemstone of petrified driftwood. 

The wood started as a pine tree in Western Australia. Some 65 to 145 million years ago, the tree fell into the mouth of a river spilling into the ocean.

The "peanuts" were boreholes made by ship worms, a type of clam, of all things.

When pieces of the wood broke off and were too water-logged to float, they sank to the bottom. The holes eventually filled with a light-colored sediment created from the shells of deceased plankton that settled to the seabed. Over time the entire piece turned to stone.

When someone admires your peanut-wood jewelry, you can entertain them with your tidbits of arcane knowledge!
