Lovely and very rare Paleosmunda is a primitive member of the Osmundoidae from the Permian Period (approximately 290 million years old) found in Central Queensland, Australia. It is a fern, species: Paleosmunda williansoni.

From the Paleozoic Era, this gemstone is the fossilized stone of Osmunda fern leaves and stems. The stone formed when a fern died and was buried by sediments. Minerals in the groundwater then permeated the fern, replacing the original organic matter and turning it to stone.
