Chalcedony is a very fine-grained variety of quartz. It has a waxy luster and appears in a great variety of colors -- usually blue-white, buff, light tan, gray, yellow or brown. It has a compact fibrous structure and fine splintery fracture.

What remains is a mineral replica of the original tree in various fantastic colors. The brilliant reds and greens are caused primarily by traces of iron oxides. Some of the best displays of petrified wood can be seen in eastern Arizona's Petrified Forest National Park.
