Petrified Wood - Tumbled Bulk Mineral

Petrified wood is a fossil formed when minerals infiltrate cavities between and within cells of natural wood. Usually infiltrated by silica or calcite, the replacement of the organic tissue with the minerals can be so precise that the internal structure as well as the external shape can still be very well-represented. The different minerals can give petrified wood a range of different colors. A beautiful specimen, this will be of enormous benefit for featuring a comprehensive rock collection in the science classroom, or for the rock collector in your family. Tumbled to create a unique and interesting look, this is a must-have addition for your science fair project on minerals!

Features:

• Produced when minerals embed themselves within cell cavities of wood
• Wide range of beautiful colors
• Smooth, tumbled surface
• Excellent as a small gift or for geology projects
