TRI Appraisal Record · Aug 2026 Certified
Tribal Kazak
Caucasus Region · Est. 1880–1910 · 4′2″ × 6′8″
// Fair Market Value
$4,200 — $5,800
▲ In range with comparable auction results
Construction
Hand-knotted
Hand-knotted rugs command premium values over machine-made — this confirms authenticity and directly impacts FMV.
Pile Material
Wool on Cotton
All-wool construction is typical for Caucasian tribal pieces. Cotton warp indicates post-1880 production — consistent with attribution.
Knot Density
6.2 / cm²
Knot density affects detail resolution and durability. At 6.2/cm², this tribal piece is within expected range — not a fine city rug, correctly priced.
Condition
Very Good
"Very Good" means pile is substantially intact with minor wear. No reweaving or repiling detected. Adds 15–25% vs a "Good" condition specimen.
Insurance Value
$8,400
Replacement cost at retail — always higher than FMV. Required by insurers. Based on comparable retail listings for equivalent pieces.
Estate Value
$4,800
Liquidation value accounting for market timing and estate discount. Used in probate distribution and IRS Form 8283 charitable deductions.

The Problem

The rug market runs on
information asymmetry.

No universal pricing standard. No verifiable credentials. No published sold-price database. The RUG Index fixes all three.

01
No pricing benchmark
Three appraisers on the same rug routinely produce valuations that differ by 200–400%. Buyers, sellers, and insurers have no objective reference.
02
No credential verification
Anyone can call themselves a rug appraiser. No licensing body, no code of ethics, no standard methodology. Fraud is rampant at the point of insurance claim.
03
No sold-price database
Unlike jewelry (Rapaport) or art (Artnet), the rug market has no published transaction database. Buyers pay what dealers ask — and dealers know it.
What We Do

Three paths to certified value

Whether you're selling, insuring, or investing in a fine rug — the RUG Index gives you the number you can stand behind.

🏷️
Certified Marketplace
List your rug for sale to serious buyers, or back it with a certified RUG Index appraisal for a documented grade and value. Sellers get fair market price; buyers know what they're paying for.

The Standard

Five pillars. One certified number.

The RUG Index grading formula is transparent and reproducible. Every appraisal uses the same five factors.

01
Origin & Region
Persian workshop cities command the highest multipliers. Origin verified by weave structure, dye chemistry, and design vocabulary.
0.8× – 3.2×
02
Material Quality
Silk, hand-spun wool, and machine-spun synthetics carry different multipliers based on fiber analysis and pile behavior.
0.4× – 2.5×
03
Age & Provenance
Antiques (100+ years) carry a 2.8× multiplier. Documented provenance adds measurable premium over undocumented pieces.
1.0× – 2.8×
04
Condition Grade
Six-point scale from Mint/Showroom (1.0×) to Damaged (0.15×). Pile height, structural integrity, repairs, and dye stability all assessed.
0.15× – 1.0×
05
Knot Density
KPSI determines fineness and labor investment. Museum-quality silk (800+ KPSI) at 1.8×. Coarse weaves (under 80 KPSI) at 0.7×.
0.7× – 1.8×

How We Read Your Rug

Knot density: the fingerprint of quality.

One of the five pillars our appraisers document from your photos — see how it moves the number.

Knot density is measured from a close photo of the rug's reverse face — the knots are countable there without disturbing the pile. It's one of the strongest single indicators of labor investment and fineness.

What appraisers look for: knots per square inch (KPSI), counted from the reverse face, cross-checked against regional weaving norms for the attributed origin.
Rule of thumb: roughly double the KPSI and you're often looking at a meaningfully higher Knot Density multiplier — see the Five Pillars above (0.7×–1.8× range).

City-workshop density — fine detail, moderate labor investment. Common in Tabriz, Isfahan, and comparable workshop production.

02 · Pile
Pile height & material

Pile material and height are read together — silk piles run thinner but denser; heavily worn wool piles lose both height and value.

Wool · 7–9mmBaseline
Silk · 3–5mmPremium
Worn · <3mmReduced
03 · Condition
The five-grade scale

Condition is graded A through E. It's the pillar most likely to move a value after the fact — undisclosed repairs are a common source of insurance disputes.

A
Mint
B
Very Good
C

D

E
Damaged
Condition spans a 0.15×–1.0× multiplier — the widest range of any pillar. See the Five Pillars section above.
04 · Values
Same rug, different numbers

Fair market, insurance, and estate values are legally distinct — each report states all that apply to your certified tier.

Real Complexity

Built for the parts that make rug valuation hard.

For the cases where origin is disputed, documentation is absent, and the difference is measured in multiples.

01
Origin misattribution
Can shift the Origin & Region multiplier from 0.8× to 3.2×
+

Regional attribution is verified by weave structure, dye chemistry, and design vocabulary — not by what a previous owner was told. Two visually similar tribal pieces can carry very different Origin & Region multipliers once examined.

Applies if: your rug's origin was passed down verbally, or a prior dealer's attribution was never documented.

02
Machine-woven detection
Hand-knotted construction carries the entire five-pillar premium
+

Machine-made and hand-knotted rugs can look similar in a photo. Construction is confirmed by knot and weave-back inspection — a step every submission goes through before a value is assigned.

Applies if: you're unsure whether your rug is hand-knotted or machine-made.

03
Three values, one rug
Fair market, insurance, and estate values each serve a different legal purpose
+

An insurer wants replacement cost. A probate court wants liquidation value. A buyer wants fair market value. Reporting the wrong one for the context is a common source of disputes — your certified report states which apply to your tier.

Applies if: you need a report for more than one purpose (e.g. insurance and eventual resale).

04
Provenance without documentation
Most inherited rugs have no paperwork
+

The Age & Provenance pillar doesn't require a receipt. Weave evidence, dye chemistry, and wear pattern establish an age range even when no documentation survives.

Applies if: you inherited the rug and have no bill of sale, appraisal, or import record.

05
Repair detection
Undisclosed repairs affect the Condition Grade pillar and insurance claims
+

Reweaving, patching, and edge repair are documented explicitly in the Condition section of your report — an insurer reviewing a claim will look for exactly this.

Applies if: your rug has any visible repair, patch, or reweave, disclosed or not.

06
Dye analysis from visual evidence
Synthetic vs. natural dye bears on the Age & Provenance pillar
+

Synthetic dyes weren't in common use before the late 1800s, so dye behavior — fading pattern, color saturation, crocking — helps bound the age range without lab testing.

Applies if: age or origin attribution is in dispute and no lab dye test has been performed.

07
Estate & legal formatting
Probate courts and the IRS each expect a specific report structure
+

A report formatted for IRS Form 8283 charitable-donation submission looks different from one formatted for probate distribution. Certified tiers are formatted to the documentation requirements of each; admissibility is ultimately determined by the receiving court or agency.

Applies if: the report is for probate, IRS charitable donation, or another legal proceeding.

08
Market-adjusted comparables
Raw auction data without adjustment can mislead
+

A single auction hammer price isn't a market. Comparable sales are weighted by condition, size, and venue before they inform a value — the same sold-price reference dealers and adjusters query through our data layer.

Applies if: someone has cited a single auction result as "the" value for your rug.

Questions

Common questions.

What's the difference between a Valuation Snapshot and a Certified Appraisal?+
A Valuation Snapshot ($35) is an instant five-pillar estimate you generate yourself. A Certified Appraisal (from $175) is reviewed and signed by a RICA-certified appraiser and formatted for insurance, estate, or legal documentation requirements.
Will my insurance company accept a RUG Index report?+
Certified reports are formatted to meet documentation requirements commonly requested by insurance carriers. Acceptance is ultimately subject to your specific carrier's and policy's requirements — we recommend confirming format expectations with your adjuster before filing.
Do I need to ship my rug for an appraisal?+
No. Certified and Legal, Estate or Tax appraisals are 100% remote — you submit photos (including the reverse face, for knot density) from anywhere in the United States.
What's the free video consultation for?+
If you're not sure which tier fits your situation, or what to photograph, a 15-minute call with an appraiser before you order can save a resubmission later. It's free and non-binding.
How do you determine origin without documentation?+
Weave structure, dye chemistry, knot type, and design vocabulary are all visible evidence — most inherited rugs have no paperwork, and the methodology is built around that reality.
Can I use a report for an IRS charitable donation?+
Certified reports are formatted for IRS Form 8283 submission. As with any donation appraisal, whether it meets the specific requirements of your filing is a determination made by your tax advisor and the IRS.
What if I disagree with the value?+
You can request a second review from another RICA-certified appraiser. Contact us and we'll walk you through the process.
