The TURKMEN tribe live in many sections of IRAN. All TURKMEN rugs and carpets have geometric patterns. The repeated "Gul" motif is the main indication of TURKMEN rugs.
The quality of TURKMEN rugs and carpets varies. Older rugs (pre-1945) are very good, but some of the newer rugs have lower KPSIs and are dyed with chemical rather than vegetable dye.
Size & Shapes:
TURKMEN rugs come in different sizes, but the majority are small (2 x 3 to 4 x 6 feet). You can also find large rugs up to large mid-size (4 x 6 to 8 x 10 feet).
Dark red is the dominant color in TURKMEN rugs and carpets. You rarely find blue backgrounds.
Soft wool; thin, tight pile.
Warps is mostly cotton; wefts is wool.
Weavers in TURKMENISTAN use Turkish knots. You should check the back of the rug because the quality of the rug depends on the number of knots, which varies, but averages around 120 KPSI(30 RAJ).
TURKMEN rugs are among the finest quality tribal rugs, so expect to pay $4-$17 Per Square Foot (PSF) for a TURKMEN rug. Keep in mind that, as a rule, the higher the KPSI, the greater is the price.
