Telling a real Persian rug from a machine-made one is easier than you would think, once you know where to look. Turn the rug over: a hand-knotted rug shows its pattern on the back as clearly as on the front, and a machine-made one never quite does. Below are the six checks you can run yourself on a rug in front of you. At Galerie Hamming van Seventer we have sold nothing but original hand-knotted Persian rugs since 1994, and this is what our advisers show customers on the shop floor.
Why hand-knotted or machine-made makes a difference
A hand-knotted rug is a one-off piece of craft that lasts for generations — a rug for life. A machine-made rug comes off an industrial loom by the hundred, is usually built from synthetic fibre such as polypropylene or polyester, and has a limited life. The distinction decides more than price and looks: a hand-knotted wool rug can be repaired, it is biodegradable, and it will often still be in use a century from now.
Six ways to tell a real Persian rug
1. Look at the back
Turn the rug over. On a hand-knotted rug the design reads just as clearly from the back as it does from the front, and you can pick out the individual knots, each one sitting slightly out of line with its neighbour. A machine-made rug has an even, tightly woven back — often with a scrim showing through, or a glued latex backing — and the pattern comes through dull and indistinct.
2. Check the fringes
On a genuine hand-knotted rug the fringes are not an addition at all: they are the warp ends — the foundation threads the knots are tied around, simply running on past the end of the rug. On a machine-made rug the fringes have almost always been sewn or glued on afterwards.
3. Look for the small irregularities
Handwork is never perfectly even, and that is exactly its charm. Slight wander in the pattern and faint bands of shifting colour — abrash, which comes from naturally dyed wool taken from different dye baths — are what give an authentic hand-knotted rug away. A machine-made rug is flawlessly regular and repeats itself exactly.
4. Judge the knot density
A finely knotted Persian rug carries thousands of knots to the square decimetre — a patch about the size of your palm — tied with the Persian, or Senneh, knot. The finer and denser the knotting, the crisper the drawing of the pattern and the higher the quality.
5. Look at the material
A genuine Persian is wool, sometimes silk, with the lanolin still in the fibre — that is what makes the pile strong and naturally resistant to soiling. The colours are often plant dyes. Machine-made rugs are usually synthetic yarn in chemical colours: they carry a hard, artificial sheen and crush flat much sooner.
6. Pick it up and fold it
A hand-knotted wool rug is heavy in the hand, supple, and falls into natural folds. A machine-made rug tends to feel stiff, and often has a dense, rubbery layer on the back.
Hand-knotted and machine-made side by side
- Hand-knotted: one of a kind; natural wool or silk; pattern legible on the back; fringes are the warp ends of the rug itself; lasts generations; repairable and sustainable.
- Machine-made: produced in series; usually synthetic; flat back with a scrim or latex; fringes sewn on; limited life.
Why a hand-knotted rug is the better buy
An authentic Persian rug is not only the better-looking object, it is the more sensible and the more sustainable purchase. Where a synthetic rug gets replaced after a few years, a hand-knotted wool rug stays in use for decades — and usually holds its value. Browse our collection of original Persian rugs, or go straight to a particular weave: Nain, Heriz, Tabriz, Kashan and hand-knotted Gabbeh rugs. And if a rug of yours ever needs bringing back to life, that is what our cleaning and restoration service is there for.

Frequently asked questions
How can I tell whether a Persian rug is really hand-knotted?
Turn it over. On a genuine rug the pattern is as legible on the back as on the front, the knots sit slightly irregularly, and the fringes run on out of the rug itself. A machine-made rug has an even back, often with a scrim or latex, and fringes that have been sewn on.
Is a hand-knotted rug worth the extra money?
Yes. A hand-knotted wool rug lasts for generations, can be repaired and usually holds its value, where a synthetic rug is normally replaced after a few years.
Are all Persian rugs wool?
Most are hand-spun wool; the finer pieces contain silk, in whole or in part. Either way the material is natural — never synthetic yarn.
Can a machine-made rug still look good?
Certainly it can. What it cannot do is be one of a kind, last, or hold its value the way handwork does. We stock nothing but genuine hand-knotted rugs.
