This is a Persian Heris rug, about 50 years old. Although these rugs are bought and sold as "Heris", the exact origin is near Heris in Northwestern Iran, a village called "Gorevan" about 55 miles north of Tabriz. Please note that your rug is a decorative piece with a wonderful geometric pattern, but colors are synthetic dyes. Here is a brief description of rugs from this region:

Heris rugs are woven in the villages of the slopes of mount Sabalan of Azerbaijan province in Northwestern Iran. Other rug producers of the region include Ahar, Sarab, Gorevan, Mehravan, Bakhshaish, Karaja, and Sharabian, just to name a few. These rugs have always been under great influence of Western markets and made accordingly. Medium and large rugs, as well as runners in all measurements, are common in this area. Rugs from this region tend to be very heavy and durable. Except for antique pieces, rugs of Heris group have cotton foundation of heavy material with two shots of weft inserted over each row of knots. Only Karaja rugs have a single weft. The region is sitting on a major deposit of copper which affects the quality of the water drunk by the sheep, thereby resulting in highest possible quality of the wool. In many cases, hand-spun and naturally-dyed wool is used; the pattern is highly geometric, with almost always a center medallion. Colors are incredibly rich using reds, royal blues, ivory, soft greens and roses, and occasionally lighter blues. Old pieces of this area are inarguably collector items. They are very desirable in Western markets, very decorative, with an average knot density of around 120-130 KPSI (knots per square inch).
