Heriz carpets are tribal hand-woven rugs produced by Azerbaijan Turkish inhabitants of the city of Heriz in Northwestern Iran. They are famous among designers because of their large vivid vegetable or soft earth tones that are woven into a geometric pattern. While no two Heriz rugs are identical, they generally tend to have a recognizable similarity in design and weaving structures. Most have a large central medallion embedded within a lighter field. Rugs made by Heriz weavers are highly prized for their marvelous design and sturdiness. Their charm lies mainly in the balance of the colors. Today, some of the largest carpets produced in Iran are from Heriz. Other descriptive names that are used are: Serapi (Rugs woven 1800-1910) Bakhshayesh or Bakhshaish (woven 1780- 1900) Goravan (woven 1850-Present) Karajdgeh (woven 1850-Present).
