The Decayed Ring of Ishtar-ibbi Breux is a 1557 years old piece made by Ishtar-ibbi Breux, a jeweler living in Istanbul / Constantinople / Byzantium.
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 Yazdanism.
This piece doesn't exist, but as a legend. It is said that in the year 916, Hezekiah Breux, the owner, made use of it in Jerusalem to empower the Breux family. Now it is lost, or broken, we will never know.
