The Decayed Ring of Abdul Dumanois is a 1973 years old piece made by Abdul Dumanois, a jeweler living in Assur.
Considering its age and the quality of the work, people consider it of no value.
It is engraved with central asian patterns and some symbols pertaining to Zoroastrianism.
This piece doesn't exist, but as a legend. It is said that in the year 1723, Mongo Dumanois, the owner, made use of it in Casablanca to empower the Dumanois family. Now it is lost, or broken, we will never know.
