A Guide for UK Buyers: How to Identify an Authentic Persian Rug

How to Guide

Published: 8 April 2025

Persian rugs have long been a symbol of luxury and refinement, adorning the homes of collectors and interior designers alike. In high-net-worth areas across the UK, demand for these exquisite designer rugs has surged.

Whether for investment or aesthetic appeal, UK buyers actively seek authentic Persian rugs to elevate their interior aesthetic. However, with this increased popularity comes a growing challenge: counterfeit rugs flooding the market.

The Problem: Fake Persian Rugs on the Rise

As demand grows, so too do the number of imitation Persian luxury rugs. Many unsuspecting buyers end up purchasing machine-made replicas or rugs crafted with synthetic materials, believing them to be genuine. Without the proper knowledge, distinguishing an authentic Persian rug from a counterfeit, can be difficult.

Below, we outline some key methods on how to verify a Persian rug’s authenticity, so you don’t unknowingly invest in a fake.

Materials Matter

Authentic Persian rugs are traditionally handwoven using natural materials like silk, wool, or cotton. These materials contribute to their durability, intricate patterns, and rich texture.

In contrast, fake Persian rugs often contain synthetic fibers, such as polyester or polypropylene, which lack the same softness and resilience. But how can a UK buyer spot a handmade vs machine-made rug, and handwoven vs synthetic material? Look for the following warning signs:

  • A plastic-like sheen or overly glossy finish.
  • An artificial, chemical-like smell.
  • Excessively uniform patterns without the slight imperfections found in unique, handmade designs.

How to Verify a Persian Rug

For over 20 years, we at London Persian Rug Company, have established our reputation as the trusted authority on authentic, handmade luxury, designer and Persian rugs in the UK. We recommend the following three tests to ensure rug authenticity:

1.     The Knot Density Test

Handmade Persian rugs exhibit a unique knotting technique. Genuine rugs have irregular, hand-tied knots, while machine-made rugs feature uniform, perfectly aligned knots. The higher the knot density per square inch, the more intricate and valuable the rug. 

2.     The Flip Test

Turn the rug over and examine the underside. Authentic Persian rugs reveal visible, uneven knots, whereas machine-made rugs display a uniform backing, often with a mesh or adhesive layer.

3.     The Burn Test (For Professionals Only)

To avoid damaging your rug or harming yourself, the burn test should only be carried out by experienced rug professionals like our team at London Persian Rug Company.

This test distinguishes wool from synthetic fibers. When a wool thread is burned, it smells like burning hair and turns to ash. In contrast, synthetic fibers melt and produce a plastic-like odour.

Five Essential Questions to Ask Before Buying a Designer Rug

Before investing in a Persian rug, we recommend asking the seller the five questions listed below. If the seller can’t easily answer with confidence, or the information they share is vague and/or unclear, take it as a warning sign and do not buy the rug!

  1. Is the rug handmade or machine-made?
  2. What materials were used in its construction?
  3. Can the seller provide provenance or certification of authenticity?
  4. What is the rug’s knot density?
  5. Does the seller offer a home trial or return policy?

Buying an authentic Persian rug is a significant investment, and with counterfeits on the rise, its vitally important that UK buyers educate themselves on the key indicators of authenticity.
