Chromium Petrified Wood.
The tag that came with sample reads as follows:
Jurassic, Arizona USA
This wood has been minerally replaced with Chromium giving it a green color. Very little of this wood has ever been found, making it very rare. This wood is a natural hygrometer, when dry it becomes a very light pale green and when wet or exposed to humidity it turns a deep green.
