This is a thematic page. It carries no Market Snapshot ratings; the Provenance risk line on each sector page remains the record and is quoted here verbatim. Substitutes sold as what they are belong on Synthetic and substitute pressure; this page is about claims that are false or unprovable.
IWhat provenance risk measures
The line on each market page is a risk, not a certainty: High means the claim is easy to misrepresent and weakly checked; Low means it is hard to fake and well verified. Gold is Medium not because bars are often fake but because the origin of doré entering the refining chain cannot be proven after the fact. 20 A racehorse is Low because the stud book is old, the registries are reliable and the animal is DNA-typed. 21
What the line is judging is the gap between a claim and a test. Every scarce asset is sold with a claim: natural, Burmese, 1926, unheated, Type A, original finish, in bond since release, this cask and no other. In some markets the claim can be tested by anyone with the fee; in others it rests on a document issued by an interested party; in a few it rests on an expert's senses and nothing else. The register in Section III sorts the 51 markets by which of these applies.
The cost of the gap is paid at exit, not at entry. The saffron page puts it plainly: the spread between the grade you were sold and the grade the buyer's laboratory assigns is the exit cost, and it can be the whole premium. 22 The same sentence could be written for oud, for pu-erh, for a cask and for a pre-2021 bottle of Japanese whisky.
IIFour kinds of claim
Provenance is one word for four different questions. A market can be safe on one and exposed on another; the register notes which.
Natural or laboratory-grown; Type A jadeite or treated; the species of sturgeon; whether the liquid in a 1926 bottle was distilled in 1926. Usually testable in a laboratory, at a price.
Exposed: diamonds, jade, whisky, caviar, manuka honey, saffron
Burmese ruby, Kashmir sapphire, Iranian saffron, Uji tencha, Russian rough, Cuban tobacco. Often an expert opinion from inclusions or chemistry, not a measurement, and reports can disagree. 3
Exposed: coloured gemstones, gold doré, rough diamonds, saffron, olive oil, tea
Refilled bottles, re-finished guitars, re-wrapped tea cakes, a watch with replaced parts, wine that left bond, a stone heated since its last report. The object is genuine; its condition is the claim.
Exposed: whisky bottles, vintage guitars, pu-erh, watches, wine and champagne out of bond, cigars
A cask certificate against a delivery order; a fossil against an export law; a falcon against a CITES permit; a painting against a restitution claim. The asset may be perfect and still not be yours to sell.
Exposed: whisky casks, fossils, falcons, ancients and raw coins, Old Masters, jade of Myanmar origin
IIIThe register, market by market
The Provenance risk line as each sector page states it, the claim most at risk, and who checks it. Each row links to its page, which carries the sources.
| Market | Provenance risk (sector page) | Claim most at risk | Who verifies, and how |
|---|---|---|---|

| Pearls | Medium | Natural vs cultured | X-ray and radiocarbon at GIA or SSEF; a report confirming natural origin is required at auction |
| Jade | High | Type A (untreated); Myanmar origin under sanction | Hong Kong Jade & Stone Laboratory or GIA report; no route at all for recent Myanmar material |
| Signed Jewellery | High | Signature and period; replaced stones | The maker's archive letter or certificate (Cartier, Van Cleef), expected before consignment; the archive number makes pieces trackable |

Fifty-one rows, one per market brief. The second column is copied verbatim from the Structure line of each page as at 29 Oct 2026; the third and fourth paraphrase its text. Where a sector page is updated, it governs.
IVWho verifies, and with what
Five kinds of verifier recur across the register. The order below is roughly the order of reliability, and it is also the order in which the Provenance risk lines fall.
| Verifier | What it does | Limit | Markets |
|---|---|---|---|
| Assay or registry | A physical test or a closed register of every unit: assay and Good Delivery lists for metals, stud books and DNA for horses, exchange warrants, Consorzio fire-brands, slabbing with population reports | Says nothing about what happened before the unit entered the register (gold doré); stops at the edge of the register (grated cheese, raw coins) | Gold, Silver, PGMs, Copper, Uranium, Racehorses, Stallions, Parmigiano, Coins (slabbed), Maple Syrup, Wagyu |
| Laboratory | An independent examination of the object: gemmological reports, X-ray and radiocarbon for pearls, radiocarbon for spirits, DNA for caviar | Origin and treatment are expert opinions, not measurements, and reports disagree 3 4; the same laboratories grade natural and lab-grown; a report costs $500–3,000 and must be renewed at each sale | Coloured Gemstones, Pearls, Polished Diamonds, Jade, Caviar, Scotch and Japanese Whisky (bottles), Olive Oil, Saffron, Manuka |
| Archive | The maker's or the trade's own records: Cartier and Van Cleef archive letters, factory build sheets, serial-number registries, catalogues raisonnés, expertising certificates, Habanos box codes | Issued by an interested party or a small committee; can be withdrawn; does not follow condition | Signed Jewellery, Watches, Classic Cars, Vintage Guitars, Art, Old Masters, Stamps, Rare Books, Cigars |
| Custody | An unbroken record of where the thing has been: bonded warehouses for wine, champagne and casks; CITES permits for falcons and caviar; Kimberley Process certificates for rough; Tracr for De Beers goods | Verifies the chain, not the contents; breaks the moment the asset leaves (wine out of bond); a certificate from the chain is not title to it (casks) | Fine Wine, Champagne, Port, Rare Whisky Casks, Falcons, Rough Diamonds, Fossils |
| Expert's senses | Nose, eye, palate and experience: oud by the water test, pu-erh by wrapper and leaf, frankincense graded by eye, truffles by the market inspector | Not reproducible, not transferable, and usually the buyer's; the holder cannot prove the claim in advance, so every buyer discounts for the doubt | Oud, Pu-erh Tea, Frankincense, Truffles, Dates, Tea, Vanilla, Handbags |
VThree cases
Where the checking failed at scale, and what the market did afterwards.
21 of 55
In 2018 a broker bought 55 bottles of rare Scotch at random from auction houses, retailers and private owners and had the liquid radiocarbon-dated at SUERC. Twenty-one were fakes or not distilled in the year on the label; every bottle claiming to be from 1900 or earlier was fake. High 1 The broker estimated £41m of fake whisky in circulation, more than the UK auction market that year. Med 1
Afterwards: radiocarbon dating became available commercially; auction houses tightened inspection; the sector page still rates bottle provenance risk High
19,000 labels
Rudy Kurniawan blended cheap Burgundy and Napa wine in his kitchen, bottled it under counterfeit labels of the rarest wines and sold it at auction from 2004 to 2012; one 2006 sale made $24.7m, a record for a single consignor. Investigators found 19,000 counterfeit labels for 27 wines. He was convicted in 2013 and sentenced to ten years. High 2 5 As many as 10,000 of his bottles may still sit in private cellars. Low 6
Afterwards: the trade's answer was custody, not testing: wine held in bond since release carries a verifiable history and wine that has left bond resells at a discount 23
Two reports, two answers
Origin is an opinion formed by comparing a stone's inclusions and chemistry with a laboratory's reference collection. Send one ruby to two respected laboratories and one may say Burma and "pigeon's blood" while the other declines to name an origin; neither is wrong. SSEF's own guidance says different laboratories may come to different results, "very similar to fields such as paintings". High 3 4
Afterwards: the auction standard for important stones is two reports, and the sector page notes each costs $500–3,000 and may come back with a different finding than the last 24
VIFour patterns in the record
The three markets rated Very high (casks, pu-erh, Japanese whisky pre-2021) and most of those rated High are markets where the proof is a piece of paper or a label issued by someone with an interest in the sale: a cask certificate from the broker, a wrapper from the factory, a label from before the standard. A test is expensive but transferable; a document is cheap and is only as good as its issuer. The casks page draws the line exactly: a certificate is a claim against the seller, a delivery order is ownership. 25
The laboratories that grade natural diamonds grade lab-grown ones; the house that makes the handbag declines to authenticate it for resale; De Beers runs the provenance ledger for its own rough; the maker's archive decides what is a signed piece. Verification and supply sit with the same party in a surprising number of markets, which is why Who sets the price and this page overlap. Hyp
Japanese whisky labelled before the 2021 standard carries a provenance discount that widens as buyers learn to read the label; wine out of bond is repriced on condition; a guitar's non-original part is a permanent deduction; a gemstone's second report can cost it an origin. Provenance risk is not static on a holding: it is re-marked every time the market's ability to test improves, and the holder who bought on the old standard pays. 26 23
Across the register, the Low lines are where a unit never leaves an accredited chain: a bar in an LBMA vault, a case in bond, a wheel in the Consorzio's warehouse, a coin in a slab. The Exit depth page finds the same markets have the deepest doors. Provenance and liquidity are the same property seen twice: a thing that can be verified cheaply can be sold quickly. Hyp
VIIIndicators to monitor
- Any gemmological laboratory adopting a common nomenclature for origin confidence, which would narrow the "two reports, two answers" gap.
- Take-up of radiocarbon dating by whisky auction houses as a condition of sale for pre-1960 bottles, and the share of lots withdrawn.
- Cask-broker insolvencies and the resulting title disputes between certificate holders and warehouses.
- Whether De Beers' Tracr ledger, with GIA's stake agreed in May 2026, becomes a condition of sale for polished stones rather than a marketing claim 27.
- Extension of New Zealand's manuka science definition to importing markets, which would move the "High outside NZ" line.
- The provenance discount on pre-2021 Japanese whisky at auction, as the clearest live measure of a market re-marking old claims.
