The valuation of an Oriental carpet is a very tricky problem, because he is both an everyday object that has specific fixed costs are based, the other a work of art that is unique and therefore everyone has an additional aesthetic value.
To the fixed costs include such products in the manufacture of all the material costs and labor costs. Important factors are the prices for raw materials (eg wool quality), location of production and the nature and extent of required personnel (whether highly skilled or semiskilled workers employed or the number of hours worked).
The aesthetic value is one of the most important value factors. Although the manual production of carpets by some is seen as a humiliation, it is the art of the carpet maker carpet according to his ideas and his expertise to make. As was the great composers of past centuries, traces the creative hand of the weaver or Knüpfer as key to the validity of a carpet.
Another factor is the value in the knotted carpet and the traditions of the respective provenances. They often represent the experience, performance and passion of a culture. This aesthetic value can be difficult to measure in a monetary unit and transmits this very reason in some carpets to make it very valuable.
The number of knots of a carpet is an important aspect in this context. The more knots per square centimeter are linked even more work must be expended.Understandably, the price of a carpet depends also on the time that is needed for its manufacture. An experienced weaver can make every day an average of 10000-14000 nodes. It therefore requires a medium quality carpet, (about 2500 knots per square inch) in size from two by three meters, about five months with a daily production of 10 000 nodes. Same size for a rug with a lower number of nodes, approximately 500 knots per square inch, it would take only one month. The number of nodes, as already mentioned one important aspect but not the most important thing. There are also coarser rugs such as Heriz, which belong entirely to the top class.
Everyone must decide for themselves what value to him and if he weighs more than is seen more as a work of art or utility value. Thus, everyone must decide for itself what it is worth the piece (see eg auctioning old antique rugs).
Properly advised and appropriate treatment of the carpets, a carpet can be doubled in value over time. The basis is the increase in value since the end of the secondSince World War II, the price increased almost steadily from Oriental rugs.
