Iranian rugs

Understanding Persian (Iranian) Rugs

"Persian" and "Iranian" describe the same thing: rugs hand-knotted in Iran, the country once known as Persia. The label is not marketing shorthand for a look or a pattern; it refers to genuine origin and to a centuries-old craft of tying individual knots onto a foundation of warp and weft threads. A true Persian rug is built one knot at a time, which is why a single piece can take months or years to weave and why no two are ever identical. At our Masab Tank showroom in Hyderabad we treat each Persian rug as the individual object it is, rather than as a unit pulled from a uniform run.

The Persian (asymmetric) knot

Persian rugs are traditionally tied with the asymmetric knot, often called the Persian or Senneh knot, where the yarn wraps around one warp and passes loosely behind the neighbouring one. Turkish and many Anatolian rugs instead use the symmetric (Ghiordes) knot, which wraps both warps. Both are legitimate hand-knotting methods used by master weavers, and the knot type is simply part of a rug's identity and regional tradition. It is the construction and the knot, not the pattern drawn on the surface, that tell you whether a rug is genuinely hand-knotted.

Regional design traditions

Iran's weaving towns each developed a recognisable character over generations. We describe them in broad strokes because every workshop and weaver varies:

• Tabriz — a historic centre in the north-west, known for a wide range from medallion and Herati patterns to pictorial and garden designs, frequently in wool with cotton or silk foundations.
• Kashan — classical floral medallions, palmettes and the Shah Abbas vocabulary in deep, saturated reds, blues and ivories.
• Isfahan — refined curvilinear floral and arabesque work in soft blues, ivory and rose, often on a silk foundation that lets the drawing stay crisp.
• Nain — elegant, restrained palettes of ivory and blue, commonly woven in wool with silk highlights that catch the light.
• Qum (Ghom) — a younger but celebrated tradition, especially prized for luminous all-silk rugs with intricate, jewel-like detail.
• Heriz — bolder, more geometric medallion designs in warm earth tones, woven in sturdy, hard-wearing wool.

These are starting points for conversation, not rigid rules. We are happy to walk Hyderabad clients and designers through the differences in person, rug in hand.

Wool versus silk

Most Persian rugs are woven in wool, and good wool is wonderfully practical: warm underfoot, naturally resilient, forgiving of foot traffic and well suited to living rooms and family spaces. Silk is a different proposition. It takes very fine detail and has a luminous sheen that shifts as you move around the room, but it is more delicate, shows pressure marks and is best reserved for lower-traffic settings, bedrooms, studies, formal sitting rooms or as a wall piece. Wool-and-silk blends sit in between, using silk to pick out highlights against a hard-wearing wool ground. For a home in Hyderabad we will always talk through where a rug is going to live before recommending a fibre.

How to judge quality and authenticity

The most honest test is to turn the rug over. On a genuine hand-knotted Persian rug the back is soft and flexible, the individual knots are visible, and the pattern reads clearly through to the reverse, mirroring the front. There is no separate cloth or latex backing glued on, because none is needed. Hand-tufted and machine-made rugs, by contrast, have their pile punched or woven through a foundation and held with adhesive, then finished with a separate backing. Knot density (KPSI) — counted by tallying knots across one inch vertically and horizontally on the back — is one useful measure, with coarser weaves around 70 to 80, medium near 100 and fine pieces above 200, though these bands are only a rough description rather than a quality grade. It is only one factor, and a rug with half the knot count can easily be the finer, more valuable piece. Wool quality, the dyes, the drawing of the design, age and condition all matter just as much.

Care, longevity and an honest word on value

Because a hand-knotted Persian rug has no adhesive to fail, it is genuinely an heirloom object, commonly lasting 50 to 100 years or more with sensible care, while glued hand-tufted rugs tend to last only around five to fifteen years as their backing degrades, especially in humidity. Rotate your rug periodically to even out wear and sun exposure, use a pad underneath, vacuum gently without a hard beater bar, blot spills promptly and have it professionally washed every few years. One honest note: most rugs do not appreciate in value. Only exceptional antique pieces reliably hold or grow worth, so buy a Persian rug for its beauty and its lifespan, not as an investment.
