You are looking at a Inner Mongolia Desert Agate skull. The skull is 1.3 inches long, from front to back. Inner Mongolia Autonomous Region, bordering to the north with both the Republic of Mongolia and Russia, is the widest province in China (by its latitude). It is the third largest Chinese province. The deserts are located in the western part of the province: the most famous and visited ones are the Badain Jaran Desert (world's 4th largest desert), Tengger Desert and Kubuqi Desert. Inner Mongolia Desert Agate is from these deserts. Its cool appearance is naturally formed by the friction of the sands blown by the winds.
