Striking Natural Petrified Wood

A natural petrified wood specimen with the grain, the growth rings and the mineral color of the original tree still held in the stone. It happens when buried timber gets slowly replaced by silica, so you end up with the exact shape of a tree that is now rock, and that never stops being remarkable. Run your thumb across the rings and you are touching something older than nearly anything else you own. No two specimens carry the same pattern, and this one is entirely its own.
