Gold has a spot price. Diamonds have a weekly price list. Jade has neither, and the reason is not that the market is immature. It is that the material refuses the conditions an index requires.

Ask what an ounce of gold costs and you get a number, current to the second, agreed globally. Ask what a carat of fine jadeite costs and you get a range spanning several orders of magnitude, followed by a question about the stone.

This is often read as a sign that the jade market is opaque or unsophisticated. It isn’t. Jade is traded in enormous volume by people who know exactly what they are doing. What’s missing is not competence or transparency. It is the set of structural conditions that make a price index possible in the first place. Understanding which conditions fail, and why, explains more about how this material behaves as an asset than any single jade price figure could.

What an index actually requires

A published price for an asset class needs three things.

• Fungibility, or a workable substitute for it: One unit has to be interchangeable with another, or the differences between units have to be reducible to a small number of agreed variables.
• A standardised description language: Buyers and sellers who cannot see the same object must be able to describe it identically and mean the same thing.
• Enough observable transactions: Prices have to be discovered repeatedly, publicly, and across the full range of the market rather than at one end of it.

Gold satisfies the first condition outright. Diamonds fail it and solve it. Jade fails all three, and the third failure is the one that cannot be engineered away.

Gold: The easy case

Gold is fungible in the strict sense. A kilogram of refined gold of a given purity is economically identical to any other kilogram of the same purity, anywhere, held by anyone. Purity is measurable, cheaply and non-destructively. There is nothing else to know.

That is why gold has a spot price and a benchmark auction, and why a holder can convert to cash at close to the quoted price on short notice. Fungibility is what makes both the price and the liquidity possible; they are the same property viewed from two angles.

Diamonds: Fungibility manufactured

Colourless diamonds are not fungible. Each stone differs. The trade solved this by compressing the difference into four variables (carat, colour, clarity, cut) grading them against published scales, and certifying them through laboratories whose results are broadly reproducible.

Once a stone is reduced to four coordinates, stones sharing coordinates become comparable, and comparable is close enough to interchangeable for a price list to work. That is the function of the weekly benchmark price lists the diamond trade has used for decades: they quote against grading categories rather than against individual stones.

This is the crucial precedent, because it shows an index does not require true fungibility. It requires a description system granular enough to be useful and standardised enough to be portable. Diamonds engineered one. Jade has not, and the obstacles are specific.

Where jade breaks

• No accepted colour scale: Jadeite’s value is dominated by colour, and there is no institutional colour grading system for it: no lettered scale, no published criteria, no laboratory that certifies colour grade the way diamond colour is certified. The premium descriptors the market runs on are trade language rather than defined categories.
• Colour is not uniform within a stone: A diamond’s colour grade applies to the whole stone. Jadeite frequently shows zoning; a vivid patch, a drift toward grey, a band running through one section. Two bangles with identical average colour can differ enormously in value depending on how the colour is distributed and where it sits on the piece. There is no way to reduce that to a coordinate.
• Translucency is a second axis with no scale: The Chinese trade vocabulary for texture and translucency is genuinely useful and applied with reasonable consistency by experienced dealers; but it is professional consensus, not a published standard, and it does not survive contact with anonymous online sellers.
• Origin cannot be determined: Geographic origin determination exists in limited form for some coloured stones. For jadeite it is not commercially available in any meaningful way, which means origin claims cannot be verified even when they are made honestly.
• Workmanship is part of the value: Jade is carved rather than cut to standard shapes. A skilled carver working with a colour zone rather than around it can multiply the value of the underlying material. Craft quality is real, significant, and unquantifiable.
• Verification is expensive relative to the median piece: Treatment status (whether material has been acid-bleached and polymer-impregnated, or dyed) is the largest single determinant of value, and it requires laboratory instrumentation to establish. Testing costs roughly the same regardless of whether the object turns out to be fine material or nearly worthless, which makes verification uneconomic across most of the market by volume.

That last point produces a classic information problem. When quality is invisible to buyers and expensive to verify, buyers rationally discount everything, which pushes good material out of the channels where verification isn’t happening. The jade trade’s answer is certification; which works, and which is precisely why the treated-versus-untreated distinction dominates pricing so heavily. But certification establishes what a thing is. It does not establish what it is worth.

The data problem

Even setting aside description, the transaction record is not what an index needs.

Auction results are the most visible public price data in jade, and they are drawn from an unrepresentative slice: the very top of the market, pieces selected by specialists precisely because they are exceptional, sold in a format designed to find the highest bidder in the room. They tell you about trophies. They tell you very little about the far larger volume of the market that clears through dealers, regional markets and, increasingly, livestreamed sales; where prices are real but not systematically recorded or published.

There is also a selection effect that runs in one direction. Pieces that fail to sell, sell privately at a discount, or never come to market at all are absent from the record. Any index built on visible sales alone would overstate the market, and there is no mechanism to correct it.

What this costs in practice

The absence of an index has three consequences that matter to anyone holding jade rather than studying it.

• The spread between buying and selling is wide, and it is not published: For assets with an index, the gap between what you pay and what you can realise is visible and usually narrow. In jade, that gap is a function of which channel you bought through and which channel you can sell through, and it is frequently large.
• Liquidity is measured in months: Selling a fine piece typically means auction consignment or a specialist dealer, on their timetable rather than yours. There is no bid waiting.
• Documentation carries disproportionate weight at resale: With no index to appeal to, a buyer’s confidence rests on what can be proved about the piece. A stone with a verifiable laboratory report and clear history transacts at a materially different level from an identical stone without one; which is unusual, and worth internalising as a structural feature rather than a formality.

So what replaces an index

Not a number. A framework.

What experienced buyers use instead is a tiered mental map: material type first, then treatment status, then colour, translucency, texture and workmanship — each of which places a piece within a range rather than at a point. It is less satisfying than a quote and considerably more robust, because it degrades gracefully. A rough position in the right tier is useful. A precise number from the wrong tier is not.

Anyone asking how expensive is jade is really asking where a specific piece sits across those variables, and the honest answer takes the form of a structured range broken down by category and quality rather than a figure.

Which is, in the end, a reasonable description of what the material is. Gold is a commodity and prices like one. Diamonds were made to behave like a commodity and price accordingly. Jade never was, and thirty years of a globalised market have not made it one. The absence of an index is not a gap in the infrastructure. It is an accurate reflection of a material where no two pieces are the same thing.
