On the fields around Rohrbach there are  unfortunately only few occurrences of small agates. Usually these are weathered porcelain-like and are only as fragments received.

While construction-workings in the 1980ies the agates shown here were found. Their peculiar banding, which places itself perpendicularly to the outer skin of the nodule, refers on similar findings in Leitzweiler and Rückweiler.
