What does “Persian rug” mean? It means the carpet is hand-knotted in IRAN and is not an imitation made in Pakistan, India, Turkey or elsewhere. This is a significant issue. Even though carpets may look the same superficially, they are not. Carpets that are made in IRAN are dyed differently, usually with vegetable pigments. In addition, the Persian knot is different. If you have a very tight budget, an imitation is probably a reasonable solution. But if you are looking for something that will keep its colour and quality for a long time, buy a “Real Persian carpet”. 9) If you change your mind for any reason, how long after purchase can you return it? We will exchange your rug after even many years of the date you did buy it from us, no limit. 10) Do they have Certificate of Authentication for the carpet and rug? Authentication Certificate Always asks for a Certificate of Authentication for your carpet, as we ask from the dealer in Iran. If you sell your carpet in the future, it will add value or it will help for your insurance. 11) How can I check the dealer s reputation? Always check the seller dealer from whom you buy a carpet.
