What information should I send if I want my rug appraised?

In order to appraise a rug or tapestry, it is necessary for me to examine it carefully and personally.
In any case, for the appraisal a photocopy of the certificate of guarantee and authenticity, the sales receipt or invoice, auction catalogues and any other document regarding the item are of considerable help. For the purpose of offering an opinion and deciding whether to carry out a real or virtual appraisal, it is essential for me to see photographs of the front and the back of the rug.

Which parts of the rug should I photograph and what format should I use?

A – clearly, the value of a rug depends not only on the materials used, but above all on the time taken to weave it, which comes down to the number of knots in it. A good quality rug for the sitting room fine Tabriz 49-50 3 m˛ (200x150 cm) will in effect have 700 rows of knots in a metre chain, that is 490,000 knots per square metre. If the single knot (the tak-baft) is used, it will take about 108 days' work (almost four months) by a skilled weaver, at a rate of about 13,500 knots per day.
B – to appraise the rug, it is necessary to have a photograph of the right side, of the details of the centre, the border and the corner design (the spandrels).
C – in order to count the number of knots, it is necessary to have photographs of the back of the rug, taken near the edge and of the fringes, with a ruler or a banknote placed exactly parallel to the selvedge of the rug. See the photographs below.
D – it is preferable for the photographs to be saved in a lightweight format, such as .jpeg.

The greh is a unit of measurement used in the area of Tabriz and is equal to 7 knots in a linear centimetre and 490,000 knots in a square metre.
