Description :
Petrified wood forms when a fallen tree is buried quickly enough that oxygen can’t reach it. Over millions of years, groundwater rich in dissolved minerals flows through the buried wood. The organic material decays cell‑by‑cell and is replaced with minerals such as quartz, chalcedony, jasper, or opal. The result is a stone replica of the original wood, preserving growth rings, grain, and even microscopic cell patterns. A few things stand out: Those long, straight lines running down the sides are the preserved grain of the original tree, showing the orientation of the wood fibers. They’re typical of conifers and other straight‑grained species. The beige, brown, and yellow tones suggest: Iron oxides (reds, yellows, browns) Silica minerals (clear to white)
These are common in petrified wood from the western United States, especially Arizona, Oregon, and Washington. That dotted pattern is the cross‑section of the wood’s cellular structure — the tiny tubes and vessels that once carried water and nutrients. When polished, this surface often looks like a mosaic of tiny pores. A glossy finish like this is usually done on agatized wood (wood replaced primarily by chalcedony), because it takes a smooth, glassy polish.Features in Your Specimen
