About Persian Rugs
Hand-knotted in Iran for thousands of years, Persian rugs are among the most valuable and technically complex textiles in the world. Understanding their construction is the foundation of caring for them properly.
Persian rugs are hand-knotted pile textiles produced in Iran — historically known as Persia — using wool, silk, or cotton foundations and pile fibers. They are distinguished by their knot density, which can range from 100 to over 1,000 knots per square inch, and by their use of natural dyes derived from plants, insects, and minerals. A well-made Persian rug is both a functional floor covering and a work of art that can appreciate in value over decades.
The tradition of Persian rug weaving dates back at least 2,500 years, with the Pazyryk carpet — discovered in a Siberian burial mound and dated to the 5th century BC — considered the oldest surviving pile carpet. Persian weaving reached its artistic peak during the Safavid dynasty (1501–1736), when royal workshops in Isfahan, Tabriz, and Kashan produced the court carpets now held in major museums worldwide. Each weaving region developed its own distinctive patterns, color palettes, and knotting techniques, creating a rich taxonomy of styles that specialists can identify by sight.
History & Origins
From northwestern Iran, Tabriz rugs are technically precise with high knot counts. They feature medallion designs, hunting scenes, and floral patterns in a wide range of colors. Often woven on cotton foundations.
Considered among the finest Persian rugs, Isfahan pieces feature intricate arabesque and floral designs on ivory or deep red grounds. Wool pile on cotton foundation; exceptionally fine knotting.
Known for their deep red and navy grounds with elaborate central medallions. Kashan rugs use high-quality wool pile and are among the most collected Persian rugs in the Western market.
Types & Varieties
From southeastern Iran, Kerman rugs are known for their soft pastel palettes and floral designs. They often feature an open field with a central medallion and are woven with a distinctive asymmetric knot.
Geometric medallion rugs from the Heriz region of northwestern Iran. Woven by village craftsmen on cotton foundations with coarser knotting than city rugs — durable and highly collectible.
Luxury rugs from the holy city of Qom, often woven entirely in silk. Among the finest and most valuable Persian rugs produced today, with extremely high knot counts.
Tabriz
Pale, refined rugs from central Iran featuring intricate floral and arabesque designs. Often incorporate silk highlights in the pile. Among the most technically accomplished modern Persian rugs.
Isfahan
Produced by nomadic and semi-nomadic tribes including the Qashqai, Bakhtiari, and Shahsavan. Geometric designs, natural wool pile, and wool foundations. Valued for their character and authenticity.
Kashan
Every persian rugs presents specific challenges. Here is what our specialists address when we work on these rugs.
Kerman
Natural dyes — particularly older aniline dyes from the late 19th and early 20th centuries — can bleed when wet. Every Persian rug is tested before washing.
Heriz
Many Persian rugs incorporate silk pile highlights that require gentler chemistry and lower agitation than wool. Mixed-fiber rugs need a carefully calibrated approach.
Qom (Qum)
Cotton foundations can shrink unevenly if dried improperly, causing rippling. Controlled flat drying is essential.
Nain
High-knot-count rugs trap fine grit deep in the pile that vacuuming cannot reach. Full submersion washing is the only way to release it without damaging the fibers.
Tribal / Village
Original Persian fringe is an extension of the warp threads — not sewn on. Proper fringe repair requires hand-knotting or hand-sewing matched fibers, not gluing.
Cleaning, Repair & Restoration Considerations
Overcasting on the sides of Persian rugs unravels with wear. Re-binding must use wool matched to the original in weight, twist, and color.
Missing pile is re-knotted by hand using wool matched to the original. Each knot is tied individually to match the surrounding density and direction.
Broken warp or weft threads weaken the rug structurally. Foundation repair must be done before pile repair to prevent further damage.
Cleaning
Faded areas can be re-dyed using natural or carefully matched synthetic dyes. This requires deep knowledge of the original dye palette and application technique.
Repair
Water damage causes dye bleeding, pile matting, and foundation distortion. Restoration involves color stabilization, re-blocking, and pile lifting.
Restoration
Moth larvae eat wool pile from the foundation up, leaving bare patches. Restoration requires re-knotting the affected area with matched fibers after treating for active infestation.
Appraising Persian Rugs
Very old Persian rugs with fragile foundations may need stabilization — backing with archival fabric — before any cleaning or repair work can begin.
