Kerman carpets (sometimes "Kirman") are one of the traditional classifications of Persian carpets. Kerman is both a city and a province located in south central Iran, though the term sometimes describes a type which may have been made elsewhere. Kerman rugs are prized for a wide range of designs, a broad palette, use of natural dyes and fibers, great tensile strength and abrasion resistance, and expert color combinations. Typical manufacturing used an asymmetrical knot on cotton foundation, but rare examples include silk or part silk piles, or silk foundations with wool pile.
