Silk Persian carpet
It is difficult to draw a precise boundary as to what counts as an exclusive carpet but most Persian carpet connoisseurs nevertheless agree on the following definition: It is a Persian carpet with exceptional detail knotted by hand in a workshop by experienced, professional carpet weavers. The material used must be of superior quality and have a knot density of at least 600,000 knots per square meter. Many of these Persian carpets have an element of silk, sometimes with gold and silver, to enhance the details, and really fine and detailed Persian carpets can be knotted entirely in silk, which ensures a fine detail to the Persian carpets that is difficult to surpass. In addition to a high knot density in the Persian carpets, there are many other factors that come into play when it comes to classifying them as exclusive. We have mentioned that the most detailed Persian carpets are knotted entirely in silk and, in Persian carpets where silk is a feature used to enhance the details, only the finest wool from sheep called cork wool is used. This wool comes from the neck of the sheep and has a high content of wool grease, making it soft and easy to work with. For the dying of the yarn only natural dyes are used obtained from plants and minerals, and combinations of dyes in the Persian carpets are chosen with the utmost care to ensure the best possible harmony.
