What is "dilmaghani"

The Dilmaghani family, the oldest existing manufacturers of hand knotted carpets and oriental rugs, can be traced back to the 1850s Qajar Dynasty, Persia. In an industry which largely produces untitled items often identifiable only by experts, the history and lineage of any name relating to specific types of rugs for so many decades is unusual. Through the 1960s, the Dilmaghani family was still designing, manufacturing and importing Persian carpets from Iran to the United States. Dilmaghani is seen as an important connection of 19th and 20th century Persian rug and carpet production in and around the cities of Tabriz and Kermān. Dilmaghani remains among the best known names of branded 19th, 20th and 21st century hand knotted carpets.
