In the area of the Inner Mongolia there are a large number of small agate deposits similarlike those in the people's Republic of Mongolia. Unfortunately little about the exact references is known, so far as the Chinese traders are quite secret. One site is producing small agates that are quite similar to those from Botswana (1, 2, 4, 5). They are showing a narrow banding, often shadow effect and rarely some colour (yellow here). The actual "chopstick agate", which have their name because of the contained pseudomorphic formations, reminding the viewer of crossed chopsticks are coming from a further reference in the Inner Mongolia (3, 6). In fact this type of agate reminiscent the "Skolezitagates" of Rhine-Hessia.
