Natural Diamond Council — The Industry's Marketing Body
Natural Diamond Council — The Industry's Marketing Body
The post-2020 successor to the Diamond Producers Association, marketing natural diamonds for member miners
The Natural Diamond Council (NDC) is the trade-marketing organisation that represents the largest natural-diamond mining companies and promotes natural-mined diamonds to consumers, retailers, and the broader trade. The NDC was launched in early 2020 as a rebranded successor to the Diamond Producers Association (DPA), which had operated under that name from 2015 onward. The principal members are De Beers Group, Alrosa (until 2022 sanctions complicated its participation), Rio Tinto, Petra Diamonds, Lucara Diamond, Dominion Diamond, and Murowa. The NDC is a marketing body, not a regulatory or certification organisation: it does not grade diamonds, does not enforce standards, and does not adjudicate disclosure or treatment claims.
Origin in the De Beers transition
The NDC and its DPA predecessor were created to fill the marketing gap left by De Beers' unilateral exit from generic-diamond marketing. From the 1947 "A Diamond Is Forever" campaign through the late 1990s, De Beers had funded generic-diamond promotion on behalf of the entire industry as a side-effect of its position as the dominant rough producer and channel manager. The dissolution of the De Beers single-channel system, completed in the 2000s, ended the company's incentive to subsidise the broader industry's marketing. The DPA was created in 2015 as an industry-funded vehicle to take over generic marketing on a shared-cost basis among the major producers.
The 2020 rebrand to Natural Diamond Council reflected two pressures. First, the rapid growth of laboratory-grown diamond supply and the LGD producers' marketing claims required a more aggressive defence of the natural-diamond category by name. Second, the broader luxury-marketing landscape had moved toward digital-first, story-led, and influencer-driven channels that the more institutional DPA structure was not designed to deliver. The NDC launched the "Only Natural Diamonds" platform — a content-led website, social channels, retailer partnerships, and influencer programmes — as its principal consumer-facing initiative.
Messaging
The NDC's core messages are three: natural diamonds are geologically rare, formed over billions of years; natural diamonds carry provenance, heritage, and emotional meaning that laboratory-grown diamonds do not; and natural diamond mining contributes meaningfully to community development in producing countries, particularly Botswana, South Africa, Namibia, Canada, and Russia. The provenance and rarity messages are designed to differentiate natural from laboratory-grown product; the community-development message addresses the secondary critique that diamond mining carries social and environmental costs that LGD avoids.
The NDC has invested in third-party studies of mining economics, environmental footprint, and community impact, including the 2014 Bain & Company report on the economic contribution of major mining operations and subsequent annual industry briefings. The studies are partisan in the sense that they are commissioned by an industry body, but the underlying data are transparent and the methodologies have been published.
Retail and trade programmes
The NDC's retailer-facing programmes include educational content for retail staff, promotional materials for store and digital use, and the Only Natural Diamonds Retailer programme that allows participating retailers to use NDC marketing assets in their own marketing. The NDC also runs trade-press relationships, exhibits at major shows including JCK Las Vegas and Vicenzaoro, and coordinates messaging with the major auction houses on natural-diamond auction lots.
The NDC does not certify retailers, does not adjudicate disclosure compliance, and does not arbitrate disputes. Those functions fall to other bodies — the FTC for disclosure under the Jewelry Guides, the Jewelers Vigilance Committee for trade-level enforcement, and the GIA, IGI, and HRD laboratories for grading and identification.
Position in the LGD debate
The NDC sits at one pole of an active commercial and rhetorical contest with laboratory-grown diamond producers, including Lightbox (the De Beers LGD brand, an unusual position since De Beers is also the largest NDC member), Diamond Foundry, WD Lab Grown, Pandora's LGD lines, and a growing field of Indian and Chinese producers. The NDC's position is that natural diamonds and LGD are different products and should be marketed and priced as different products; the LGD producers' position is that the products are physically identical and that natural-only marketing is anachronistic. Regulatory bodies — principally the FTC in the United States and the European Commission — have intervened to require clear disclosure that LGD diamonds are laboratory-grown, but have stopped short of prohibiting the use of "diamond" without qualifier for LGD product, which the natural-side trade had advocated.
The Russian invasion of Ukraine in 2022 and the subsequent sanctions on Alrosa diamonds added a complication: the NDC's largest non-De Beers member became politically and commercially difficult to feature in marketing, and the NDC's messaging shifted to emphasise non-Russian member production. Alrosa's formal status within the NDC has been a matter of public reporting that has shifted over time.
The trade's view
Within the trade, the NDC is regarded as a marketing body with limited regulatory or technical role. Its content is consumed by retailers and consumers; its lobbying and policy positions are taken seriously in disclosure debates; but its claims, like all trade-body claims, are read with awareness of who is funding them. The NDC's website (naturaldiamonds.com) and its newsletter are useful sources for current trade messaging and for consumer-facing narrative; the GIA, the World Diamond Council, and the Kimberley Process remain the principal references for technical, certification, and policy questions.
