The Caucasian carpets are from the areas south, east and north of the mountain chain of the Caucasus (Russia, Armenia, Azerbajdzan). The significance of these beautiful carpets are their geometrical patterns, often with an imaginative and plentiful way of expression. Sometimes curvilinear animal and pattern figures occur in the carpets.
The older Caucasian carpets are made with handspun yarns of wool as well as the warp, weft and pile. The natural colours are both clear and strong. Good wool quality and Turkish knots make the carpets durable and they have a good reputation. In newer carpets, made after 1925, the warp is of cotton, with syntethic colours that are bleached and fewer and simplified patterns are used. The carpets are fairly durable, but less interesting from an artistic point of view. (http://www.carpetencyclopedia.com)
