YAZD rugs and carpets usually have a single medallion in the center. Very rarely, one can find a YAZD carpet with small medallions scattered all over the carpet.
YAZD rugs and carpets are of very good quality and are quite durable, so they are an excellent choice for a high traffic area.
Size & Shapes:
YAZD rugs and carpets come in different sizes, but the majority of them are mid-size (4 x 6 to 8 x 10 feet). It is very hard to find good, large size YAZD carpets (10 x 18 feet) except for some antique ones.
Strong red in the background and a brownish border are the main indicators of a YAZD rug or carpet. Pink is the color of choice to create an abstract background in many rugs from YAZD. Other colors such as soft green and khaki appear in newer ones. Blue is a rare color in YAZD rugs and carpets.
YAZD rugs and carpets usually have thick pile.
Warps is mostly cotton; wefts is usually cotton.
Weavers in YAZD use Persian knots. The quality of the carpet depends on the number of knots, which varies, but averages around 120 KPSI (30 RAJ). In good antique ones, you can find higher KPSI (270-324)..
YAZD rugs and carpets are fine and beautiful. Expect to pay $3-$12 Per Square Foot (PSF) for a very prized and beautiful carpet from YAZD. Keep in mind that, as a rule, the higher the KPSI, the greater is the price.
