Birjand is a small city in the Khorasan province of northeastern Iran. The Birjand rugs typically have a very elegant model, similar to Herati but with a European feel. These usually have a stylized round central medallion sitting in an open field of small fish in a sea of beige. Borders repeated resemble those of the Mahi, but the Birjand is more curvilinear. In general, they are very complicated and detailed. Color schemes include beige and navy blue, with hints of burgundy and salmon.
