Isfahan rugs are knotted on either silk or cotton foundations, with up to 400 Persian knots per square inch, using exceptionally good quality (often Kurk) wool for the pile, which is normally clipped quite low. Isfahani rugs and carpets usually have ivory backgrounds with blue, rose, and indigo motifs. These rugs and carpets often have very symmetrical and balanced designs. They usually have a single medallion that is surrounded with vines and palmettos. These rugs and carpets usually have excellent quality. The most famous master weaver in Isfahan is Serafian.

Isfahan, an Iranian city has long been one of the centres for production of rugs. This city claims to be a world heritage site and produces the most consistently fine wool pile rugs made anywhere in the world today. Their quality may be matched by individual items from the other major Persian workshop groups, but Isfahan produces far fewer poor quality rugs.
Some Isfahani rugs became known in Western Europe as "Polish rugs". This name refers to carpets woven with silk, golden and sliver threads in Persia during the 16th-18th centuries and exported to the Polish-Lithuanian Commonwealth. They were commissioned by wealthy Polish noblemen and decorated with their coats of arms. Some of them were later resold to West European buyers who were often convinced of their Polish origin, hence their name.
