Tabriz is one of the oldest carpet-making cities in Iran and is known for its diverse array of floral and geometric designs. Given its diversity it is impossible to single out one distinct Tabriz design, but what they all have in common is a masterful level of craftsmanship. Unlike their tribal counterparts, weavers in cities like Tabriz can spend months or even years on their rugs, allowing them to create a level of intricacy and detail that is truly spectacular.
 
This rug has a dark navy background which is contrasted by the purple and terracota used for the all-over herati pattern and border.
