This is semiprecious stone Petrified Sycamore Wood or fossil Platanus.

Also known as Badger Pocket Fossil Wood, this Petrified Wood was found in the 1960's and is now inaccessible and very rare.

This unique Petrified Wood is found only in one place in the world, from the Squaw Creek forest southeast of Kittitas, Washington.

Only this location in Washington produces this semi precious gemstone material Petrified Sycamore Wood that, when designer cabochons are cut right, the cabochons will have this unique "feather" pattern.

This petrified wood is from the Miocene age and about 15.5 million years old.

Tree trunks were buried under several hundred yards of sediment. Over the course of time the wood was replaced by cryptocrystalline quartz, largely chalcedony (jasper). During the replacement process by silica carried in underground waters, even the most minute details of the woody structure was preserved.
