I did a search on Google and it says Serapi is a trade name given to better quality Heriz rugs thought to have been woven before 1900. In the United States, the highest quality of Heriz rugs are called Serapi. The name Serapi originates from the village of Serab.

I hope this helps you. Have a nice day :)

I think this post is , like many others from this poster, a commercial business drumming up interest with their questions. I don’t think this is a legitimate and genuine question.
