A ring arrives in a recycled cardboard box. That may be worth telling customers, but it says little about the gold or gemstone inside. For a jeweller writing a product description, the challenge is making a useful claim without allowing it to promise more than the evidence supports.
The Competition and Markets Authority’s January 2026 guidance on green claims across supply chains builds on the existing Green Claims Code. It makes the responsibility clear: retailers need to take steps to verify environmental claims, including information passed on by suppliers. Copying a manufacturer’s wording does not remove that responsibility.
For a small jewellery business, the product page is a sensible place to start. Can someone reading it understand exactly what the claim covers, and what supports it?
Explain what “ethical” means for the ring
A customer asking about ethical jewellery may be concerned about working conditions, gemstone sourcing or environmental impact. Those questions need different evidence.
Different gemstone types can require different sourcing evidence. Lily Arkwright’s page on ethical engagement rings, for example, brings together lab-grown diamond, moissanite and lab-created coloured gemstone designs. For a retailer grouping materials this way, suppliers and supporting records may differ. Evidence for one material should not automatically be applied across the range.
A useful answer identifies the relevant supplier standard or sourcing process and explains its scope. Lab-grown describes how a diamond was formed; it does not, by itself, establish the environmental impact of the finished ring. Equally, an assurance about working conditions should not be presented as evidence of lower carbon emissions.
Separate claims about the stone, metal and packaging
The CAP guidance on environmental advertising explains that broad claims normally need evidence covering a product’s full life cycle. A narrower claim can be appropriate, provided its limits are clear and it does not give a misleading impression of the overall impact.
For jewellery, that means being precise about the component. If the evidence concerns recycled gold in the band, say so. Establish whether a quoted percentage refers to the gold content or the whole alloy, and whether it also covers the claws and other metal parts.
Imagine a supplier confirms recycled gold in a ring’s band but provides no corresponding information about its platinum setting. Describing the entire ring as made from recycled precious metals would go beyond that evidence.
Keep “recycled” and “recyclable” distinct: the first describes the material used; the second describes whether it can be processed for use again. A verified “recyclable cardboard outer box” claim, with any recycling conditions explained, is more precise than a green badge beside the ring’s name.
Ask suppliers for evidence that matches the product
A supplier’s general sustainability brochure may not answer a question about the ring being sold. Ask which products, components and production periods the evidence covers. Where certification is cited, check what was assessed and whether the relevant certificate is current.
The CMA advises businesses that cannot verify a claim to consider whether they can make a different claim that they can substantiate. If no environmental claim can be supported, withhold it or remove it while the evidence gap is resolved. Narrower wording only helps when that statement can itself be verified.
Keep a record of the proposed sentence, its supporting document, the affected product codes and the date it was checked. Someone updating the website can then see which evidence belongs to which description, without searching through a colleague’s inbox.
It also makes gaps easier to spot. A document covering one metal supplier should not automatically follow a design when the workshop changes suppliers.
Put the explanation beside the claim
Customers should not have to open a general sustainability policy to discover that a prominent claim applies only to the packaging. The Green Claims Code checklist calls for clear qualifications and accessible supporting information.
Keep the essential limit close to the wording customers see. Longer evidence can sit behind a clearly labelled link, but the short description should remain understandable on its own.
Read the page after changing the metal or gemstone option, too. If a claim applies to one version, a shared description must not make it appear to cover every selectable ring. Check the mobile view, where a qualification may be much further from the headline than it appears on a desktop.
Sales staff need the same explanation. A careful product page loses its value if an appointment or chat response turns a limited claim into a promise about the whole ring.
Review the wording when the range changes
Start with one collection and follow a product from its supplier paperwork to the website, advertising and sales conversation. Give someone responsibility for checking the wording whenever its materials, supplier or supporting evidence changes.
Before the wording goes live, ask a colleague to explain it as they would to a customer. They should be able to say which part of the ring it covers and point to the supporting evidence. That is a better starting point for a sales conversation than leaving either person to guess what “green” means.
