Petrified Wood Cabachon, Karnes County, Texas
Beautiful cabachon featuring a variety of agatatized petrified wood from Karnes County, Texas that has been dubbed "Shrinkwood".
This cabachon was cut and polished by Richard Dorsey, a member of the Austin Gem and Mineral Society.
Additional Information: Shrinkwood is a local Texas name given to petrified wood that has been partially decomposed and fractured and then resealed with more silica. In its most perfect form, the fractured sections of wood are almost perfect hexagons giving it the scientific name, "hexagonally fractured petrified wood". In some cases the brecciated sections retain the original wood pattern and in others the original pattern is barely discernible.
