Diamond Standard is a regulated commodity product launched in 2018 that converts natural, laboratory-certified diamonds into a fungible, exchange-tradable instrument. Each unit — marketed as a Diamond Standard Coin or Diamond Standard Bar, and represented digitally by the token ticker DIAM — is backed by a standardised physical basket of natural diamonds graded by the Gemological Institute of America (GIA) or other recognised gemmological laboratories, and held in secure, audited vaults. In 2021, Diamond Standard received a no-action letter from the U.S. Commodity Futures Trading Commission (CFTC), a regulatory milestone that positioned the product as a legitimate commodity instrument under U.S. law and distinguished it from the broader, largely unregulated landscape of cryptocurrency and tokenised-asset projects.

The Problem Diamond Standard Was Designed to Solve

Natural diamonds have historically resisted commoditisation for several structural reasons. Unlike gold or platinum, no two diamonds are identical; price is a function of the interplay between the four Cs — carat weight, colour, clarity, and cut — as well as provenance, fluorescence, and laboratory origin report. This heterogeneity has meant that diamonds lack a single, transparent spot price. Secondary-market liquidity is fragmented across dealers, auction houses, and online platforms, with wide bid-ask spreads and no centralised clearing mechanism. Institutional investors seeking exposure to diamonds as an asset class have had no standardised vehicle comparable to a gold exchange-traded fund or a futures contract.

Diamond Standard's founding premise is that a carefully constructed basket of diamonds — selected algorithmically to represent a statistically consistent cross-section of the market — can behave as a fungible unit even though no individual stone within it is interchangeable with any other. By defining the basket composition through a transparent, rules-based methodology and anchoring each basket to GIA-graded stones, the product introduces the price discovery and fungibility that commodity markets require.

Structure and Composition

Each Diamond Standard Coin contains a fixed number of natural diamonds selected through a proprietary algorithm that optimises for market representativeness and value stability. The diamonds are graded by GIA or equivalent recognised laboratories, ensuring that each stone's characteristics are independently documented. Physical custody is maintained in insured, third-party vaults, and the ownership of each coin or bar is recorded on a blockchain ledger, with the digital token (DIAM) serving as the on-chain representation of that physical entitlement.

The Bar format contains a larger basket than the Coin and is targeted at institutional participants, while the Coin is positioned for broader retail and professional investor access. Both formats are designed so that the holder retains the right to redeem the physical diamonds underlying the token, preserving the direct link between the digital instrument and the tangible asset.

Basket composition is periodically recalibrated through what the company describes as a blind auction mechanism, in which diamond suppliers submit stones meeting defined parameters. This auction process is intended to establish a market-clearing price for each basket configuration, contributing to the price transparency that has historically been absent from the diamond trade.

Regulatory Status and the CFTC No-Action Letter

The CFTC no-action letter, issued in 2021, is the most consequential regulatory development in the product's history. A no-action letter is a formal communication in which the CFTC's Division of Market Oversight indicates that it will not recommend enforcement action against a party for operating in a specified manner. In Diamond Standard's case, the letter addressed the commodity status of the product, effectively acknowledging that Diamond Standard Coins and Bars could be treated as commodity instruments — placing them in the same regulatory category as gold, silver, and crude oil — rather than as securities subject to Securities and Exchange Commission oversight.

This distinction matters considerably for institutional adoption. Commodity classification opens pathways to futures markets, commodity exchanges, and regulated derivatives products. It also clarifies the compliance obligations of broker-dealers, custodians, and fund managers who might otherwise face ambiguity about how to hold or trade the instrument. The no-action letter does not constitute formal CFTC approval or endorsement of the product, but it represents a meaningful degree of regulatory clarity in a space where such clarity has been scarce.

Market Context: Diamonds as an Asset Class

The broader investment case for natural diamonds rests on several well-documented characteristics: relative scarcity of high-quality rough, the finite nature of major producing mines (several of the world's largest, including Argyle in Western Australia, have closed or are in decline), and historically low correlation with equities and fixed-income instruments. However, realising these theoretical investment attributes has been difficult in practice without a liquid, transparent vehicle.

Diamond Standard's approach is not the first attempt to create diamond investment products — exchange-traded diamond funds have been proposed and in some cases launched in various jurisdictions over the past two decades, with mixed results — but the combination of physical backing, laboratory certification, blockchain-based ownership records, and formal commodity-regulatory engagement represents a more structurally rigorous approach than most predecessors.

The product also arrives in a market context shaped by the rapid growth of laboratory-grown diamonds, which has introduced significant pricing pressure on lower-quality natural stones and sharpened the industry's focus on the investment and rarity narrative for natural, high-quality material. Diamond Standard's basket methodology explicitly targets natural diamonds, and the GIA grading requirement ensures that laboratory-grown stones — which GIA reports clearly identify — cannot be substituted into the baskets.

Criticisms and Limitations

Diamond Standard has attracted scrutiny on several fronts. Critics within the gemmological and investment communities have questioned whether a basket of commercially graded diamonds can truly achieve the price stability and liquidity of established commodity benchmarks, given that diamond prices remain subject to fashion, consumer sentiment, and the pricing policies of major producers. The absence of a deep, liquid futures market — which underpins price discovery for metals and energy commodities — means that the basket's market value is still ultimately anchored to a relatively illiquid underlying asset.

There are also questions about the long-term behaviour of basket composition. As market conditions shift, the algorithmic selection criteria may need to evolve, raising questions about consistency of the instrument over time. Additionally, while blockchain-based ownership records offer transparency and transferability, they introduce the technical and custodial risks associated with digital-asset infrastructure, including smart-contract vulnerabilities and the operational complexity of redemption processes.

From a gemmological standpoint, the use of commercially graded diamonds — rather than investment-grade or collector-quality stones — means that the baskets are composed of material whose value is sensitive to retail demand cycles rather than the rarity premiums that characterise exceptional gems. This is a deliberate design choice aimed at maximising the size and liquidity of the addressable market, but it means that Diamond Standard is not a proxy for the fine-gem segment of the diamond market.

Significance for the Gem and Jewellery Trade

For the broader gem and jewellery industry, Diamond Standard represents a notable experiment in applying commodity-market infrastructure to a historically craft-oriented trade. If the model achieves sustained liquidity and institutional adoption, it could influence how diamonds are priced, financed, and held throughout the supply chain — from rough producers and polishers to retailers and end investors. It also establishes a precedent that other gem categories — coloured stones, pearls, or even jade — might eventually follow, though the standardisation challenges are considerably greater for those markets.

The product's reliance on GIA grading as a foundational quality anchor underscores the continuing centrality of independent laboratory certification to any credible diamond investment framework. Without a universally trusted grading standard, no basket-based commodity structure could achieve the fungibility it requires.
