Natural Diamond Council Becomes The Diamond Collective

The Natural Diamond Council has renamed itself The Diamond Collective. The change was announced on Tuesday 22 September 2026 and reported the same day by the trade title JCK, which noted that the new logo, a purple palette and the motto "Old Soul, New Energy" appeared across the organisation's social pages during the morning without a press launch. The body remains an industry-funded not-for-profit. Its stated aim, in the words of chief executive Amber Pepper, is "more people choosing natural diamond. More often."

For anyone shopping for natural diamonds in Hatton Garden, the practical question is not the logo. It is whether a name that no longer says natural changes anything about what a buyer should ask across the counter. It does not. The rules on describing laboratory-grown diamonds, the certificate that states a stone's grade and the hallmark on the mount are unchanged. What the rebrand does signal is how hard the natural side of the trade now expects to fight for the engagement ring purchase.

What changed on 22 September

The Natural Diamond Council became The Diamond Collective, keeping its funding model and its purpose but dropping the qualifier from its name. According to its own statement, quoted by JCK, the organisation has three goals. Unite the producers, retailers, brands and designers around shared growth priorities. Protect consumer confidence through clarity and facts, and clearly differentiate diamonds from synthetic diamonds. Inspire desire through culture, creativity and storytelling that leads to a purchase.

Two structures come with that. A Global Steering Committee is to bring voices from inside and outside the industry into the organisation's decisions. A first fashion partnership is promised for 2027, building on relationships with designers and fashion houses. JCK also notes earlier announcements that carry over, including a Trustmark for natural diamonds, a Diamond Desire Index intended to measure whether the campaigns work, and a bigger marketing push behind World Diamond Day.

Why the word natural was dropped

Pepper's explanation is direct. "For too long, we have played defense, allowing the original to be defined by a qualifier when in truth there is no worthy comparison. Diamonds are the original. They do not need a qualifier," she said in the statement reported by JCK. The context is not flattering for the mined side of the trade. JCK reports that natural diamond prices have fallen, that De Beers has paused some mining operations while other mines close, and that lab-grown diamonds are taking market share, most visibly in engagement rings sold in the United States.

Branding specialists quoted by JCK split on whether the move helps. Keran Smith of LYFE Marketing argued that a name matters to consumers only when it signals something meaningful, and that the industry's larger problem is giving people a stronger reason to want natural stones at all. Andrea Quagliato Lebrón of Might and Matter called the shift from Council to Collective a strong one for a younger audience, but warned that removing the word natural is a risk, because The Diamond Collective could now describe almost anyone in the category, including sellers of laboratory-grown stones.

What stays the same at a Hatton Garden counter

A trade body's name has no legal standing in a British shop. Three things do. First, under UK consumer protection rules a laboratory-grown diamond must be described as such, clearly and next to the word diamond, so a buyer can rely on the description on the ticket and the invoice rather than on any campaign. Second, the grade of a stone comes from the certificate that travels with it, and a colour or clarity grade means nothing without the name of the house that issued it. Third, the mount is covered by the hallmark, which certifies the metal fineness, not the stone.

Those three checks are the same whether the organisation behind the advertising calls itself a council or a collective. The interpretation offered here is that the rebrand is a marketing decision aimed at demand, and a buyer's protection sits in documents, not in marketing.

Where Hatton Garden already sells both

The district has not waited for the trade body to settle the argument. Several Hatton Garden jewellers in this directory sell natural and laboratory-grown stones side by side and say so plainly. Austen & Blake at 8 Greville Street offers engagement, wedding and fashion diamond rings in both natural and lab-grown diamonds. Luxury Lab Collection at 28a Hatton Garden specialises in laboratory-grown stones alongside a wider diamond selection.

On the natural side, Abrahams Diamond Jewellers at 110 Hatton Garden has made diamond jewellery in the district for more than 30 years, and Finecraft Jewellers at 10 Greville Street was founded in Hatton Garden over 60 years ago. A buyer who wants to compare the two categories can do it on one street, in an afternoon, with both stones and both certificates on the same counter.

What to ask before you buy

Ask which house issued the diamond certificate and check the report number against that house's own database. Ask for the stone's description in writing, with the words laboratory-grown or natural stated next to the word diamond. Ask to see the hallmark on the mount and what fineness it records. Ask what the shop's own view is on the price gap between the two categories today, with the date, because that gap has moved and will move again. None of those questions depend on what the trade body calls itself this year.
