Persian Heriz Rugs: The Complete Guide.

Heriz is one of a handful of Persian rug traditions that Americans reliably recognize on sight. The bold angular medallion, the deep madder ground, the ivory corner spandrels — if you grew up seeing "traditional" Persian rugs in New England living rooms and Manhattan libraries, you were probably looking at Heriz. Here's the full story.

01 — OriginThe Heriz district.

Heriz refers to a district of villages in northwest Iran, east of Tabriz, in the Azerbaijan region. The name covers roughly 30 villages that produce rugs in the same regional tradition, with the main village called Heriz (also spelled Heris). Related villages include Ahar, Bakhshaish, Gorevan, Mehraban, and Serapi.

Rug weaving in Heriz district traces back centuries, but the tradition reached its greatest fame in the late 19th and early 20th centuries when Heriz rugs became the preferred large-scale Persian rug for European and American formal rooms. The scale was practical — Heriz workshops produced 8x10, 9x12, and 10x14 rugs at prices middle-class buyers could afford — and the durability suited households with children, dogs, and daily use.

02 — DesignThe angular medallion.

The classical Heriz design is a large geometric medallion on a densely patterned field, with strong corner spandrels. The defining features:

• Angular, geometric drawing. Unlike the flowing curves of Kashan or Isfahan, every element in a Heriz is drawn with straight lines and sharp angles. This is by necessity: the low KPSI count doesn't allow curvilinear detail.
• Bold central medallion. Usually a stepped diamond or hexagon, with pendants extending vertically.
• Prominent corner spandrels. Quarter medallions in each corner echo the central form.
• Field densely filled with stylized floral motifs. Palmettes, rosettes, and vines drawn geometrically.
• Multiple borders. Usually 3-5 borders with turtle, palmette, or geometric floral patterns.

Some Heriz production omits the medallion entirely (allover Heriz) or uses a different center form. The "Serapi" tier — older, finer Heriz — often features more elaborate drawing and softer colors than standard Heriz.

03 — Materials & ConstructionHeavy wool, cotton foundation.

Heriz uses thick, coarse wool pile on a cotton foundation. The wool is from local mountain sheep — not the fine long-staple wool of Kashan, but a heavier, more durable fiber that suits high-traffic use. Cotton warps and wefts give the rug structural stability without excessive weight.

Heriz uses the Turkish (symmetric) knot, which is stronger and more durable than the Persian knot — matching the tradition's emphasis on longevity over fine detail. Typical KPSI ranges:

• Standard Heriz: 80-140 KPSI
• Fine Heriz: 140-180 KPSI
• Serapi tier (antique): 100-160 KPSI (finer wool, better drawing, not necessarily higher count)

These are LOW knot counts by Persian standards — but that's not a defect. Heriz was designed for durability and bold visual impact, not for fine detail. Judging a Heriz by KPSI is judging the wrong metric. See our KPSI guide for context.

04 — PaletteMadder red, ivory, and rust.

The classical Heriz palette is madder red field with ivory or cream medallion and corner spandrels, accented with rust, terracotta, deep blue, and small amounts of green. This is the color combination most Westerners think of as "the Persian rug palette."

Traditional Heriz uses natural dyes throughout — madder root for red, indigo for blue, walnut for brown, weld for yellow. Colors have subtle abrash variation and age beautifully to softer, richer tones. Some modern Heriz production uses synthetic dyes, which can look harsh next to natural-dye antiques.

The "Serapi" tier is known for softer, more pastel palettes — often paler reds, salmon tones, and dusty golds. These softer colors are one reason Serapis command higher prices than standard Heriz.

05 — The Serapi TierWhat "Serapi" actually means.

"Serapi" (from the village of Serab or Sarab in the Heriz district) is a marketing term for older, finer, and more decoratively drawn Heriz rugs from roughly 1880-1910. The term isn't perfectly standardized — different dealers use it slightly differently — but generally, a Serapi:

• Was woven before roughly 1910
• Has finer wool and slightly higher knot count than standard Heriz
• Features softer, more elegant color palettes
• Shows more sophisticated drawing, especially in the medallion and borders
• Often has fewer, larger design elements (less crowded than typical Heriz)

Serapis have become one of the most collected Persian rug categories in the last 20 years. Prices have risen dramatically as decorators and design magazines have featured them. A good Serapi can now cost 2-3x what a standard antique Heriz of similar size costs.

06 — Market TiersSerapi, antique, semi-antique, and modern Heriz.

07 — PricingSerapi commands the premium.

• Serapi 9×12: $15,000-60,000+
• Serapi 10×14 (rare): $25,000-100,000+
• Antique standard Heriz 9×12: $5,000-18,000
• Semi-antique Heriz 9×12: $3,000-9,000
• Modern Heriz 9×12: $2,000-6,000
• Room-size Heriz 12×18+ (antique): $20,000-80,000+

Heriz is one of the few Persian traditions where large room-sizes are relatively common in the antique market — this is because Heriz was specifically produced for large European and American formal rooms. This makes it a good hunting ground for buyers who need 10x14, 11x14, or larger antique pieces.

08 — Identifying AuthenticSigns of a real Heriz.

• Angular, geometric drawing. Every line is straight. If you see flowing curves, it's not a Heriz.
• Heavy, coarse wool. Thick pile, dense hand. Not smooth or fine.
• Turkish knot construction. Symmetric knots on the back.
• Cotton foundation. Not wool foundation.
• Low KPSI. 80-160 range. Higher KPSI suggests a different region being sold as Heriz.
• Bold color palette. Madder red dominates. Ivory medallion. Rust and blue accents.
• Multiple concentric borders. Usually 3-5 borders.

09 — CareMade for daily use.

Heriz rugs are among the most durable Persian pieces produced. Standard care applies but Heriz tolerates more use than most fine Persian rugs. Weekly vacuum, annual rotation, quality rug pad, professional cleaning every 3-5 years. Heriz can safely go in living rooms, dining rooms, family rooms, and other high-use spaces — that's what it was made for.
