Persian Heriz Style Hand-Knotted area rug

This is a large rectangular hand-knotted wool area rug, likely a Persian Heriz style or Serapi-inspired piece, characterized by its bold geometric patterns and vibrant color palette. The rug features a dominant brick-red or terracotta field decorated with a repeat 'all-over' floral and geometric motif. It is enclosed by a wide, contrasting midnight-blue main border containing alternating large rosettes and stylized floral elements in cream, gold, and light blue. The construction appears to be high-quality wool pile on a cotton foundation, indicated by the visible light-colored fringe at the ends. Regarding condition, the rug shows signs of moderate wear consistent with age, particularly along the edges where the binding may be loosening. There are visible creases across the surface suggesting it has been folded or moved recently, and some areas of uneven pile height may indicate high-traffic use. The fringe is slightly frayed but mostly intact. The craftsmanship suggests a mid-20th-century origin, showcasing the traditional weaving techniques of Azerbaijan province in Northwest Iran. The dyeing appears consistent, though there may be minor abrash (natural color variations) throughout the red field, which is often a sign of authentic hand-dyed wool.

I have examined the digital representation of this large Persian Heriz-style hand-knotted rug. The piece exhibits the classic 'all-over' geometric floral aesthetic associated with the Azerbaijan province, featuring a robust terracotta field and characteristic midnight-blue main border. The construction appears to be high-quality wool on a cotton foundation, typical of mid-20th-century Northwest Iranian production. The visual evidence of 'abrash' or natural tonal shifts in the red field suggests the use of high-quality, potentially vegetable-based dyes. My assessment notes moderate wear, specifically edge binding loosening and surface creasing, which slightly diminishes the retail value but confirms its history of use. Current market demand for Heriz and Serapi patterns remains strong due to their durability and timeless design. Comparables for a rug of this size and vintage range from $2,000 to $4,500 depending on pile depth and origin. However, digital examination has limitations; I cannot definitively verify the knot density (KPSI), the presence of underlying structural repairs, or the exact wool quality. A final authentication would require an in-person physical inspection to examine the back for 'knotting technique' and 'foundation integrity,' as well as provenance documentation to confirm its specific village of origin. For a formal insurance valuation, I would also need to perform a burn test on the fringe to confirm material purity and check for synthetic dye bleeding.
