The Historic Ring of Mert Deirdreoui is a 3328 years old piece made by Mert Deirdreoui, a jeweler living in Ur.
Considering its age and the quality of the work, people consider it of the highest value.
It is engraved with central asian patterns and some symbols pertaining to Folk religion.
This piece doesn't exist, but as a legend. It is said that in the year 236, Shanti Deirdreoui, the owner, made use of it in Beijing to empower the Deirdreoui family. Now it is lost, or broken, we will never know.
