How Much Is a Persian Rug Worth?

Persian rug values are determined by a specific set of measurable factors, which makes this category more objective than most antiques once you know what to look for. Origin is the first, and rugs are named for the city or region where they were woven, with Isfahan, Nain, Qum, and Tabriz at the fine end and tribal weavings from Hamadan, Heriz, and various nomadic groups occupying different markets. Knot density, counted per square inch on the back, is the clearest single quality indicator and ranges from around 30 for coarse tribal rugs to over 500 for the finest silk city pieces. Materials matter enormously, with silk above fine wool above ordinary wool, and the foundation being cotton or silk rather than wool in finer pieces. Age adds value only when combined with quality and condition. The most important commercial distinction is hand-knotted versus machine-made, and it is instantly checkable by looking at the back and the fringe.

Origin and weaving quality set the framework, and the named city weaves command consistent premiums over village and tribal production. Knot density is the most objective quality measure and is counted directly on the back, with higher counts allowing finer detail. Materials matter greatly, and silk pile on a silk foundation is the top tier. Dye type is a major factor, since natural vegetable dyes age into rich, varied tones while early synthetic dyes can fade badly or run, and this is checked by examining the color at the base of the pile versus the tip. Age adds value when combined with quality, and antique pieces from before roughly 1930 with natural dyes command large premiums. Condition covers pile height, foundation exposure, moth damage, repairs, and any color run from water damage. Size affects price non-linearly, with unusual sizes sometimes harder to sell despite quality.
