Petrified Wood Tumblestone
Petrified Wood, which is technically a fossil and a crystal, comes from the trunks and branches of ancient wood. These fossilized specimens have had their chemical body replaced by another mineral over time. The minerals that replace the physical wood are often Agates or Chalcedony/Quartz, but can rarely be found opalized.
Please note: As this is a natural crystal/stone, tumbles will vary in colour and pattern. Picture is an example only. I will select a tumble for you.
