The Historic Ring of Mainza Batterberg is a 1354 years old piece made by Mainza Batterberg, a jeweler living in Amud.
Considering its age and the quality of the work, people consider it of considerable value.
It is engraved with african patterns and some symbols pertaining to Berber religion.
This piece doesn't exist, but as a legend. It is said that in the year 795, Orisa Batterberg, the owner, made use of it in Amud to empower the Batterberg family. Now it is lost, or broken, we will never know.
