Amazon UK Introduces New Attribute Rules for Jewellery Listings to Improve Accuracy
Sellers must classify items as fine or fashion and provide detailed material and pearl information
Amazon UK has rolled out new mandatory attribute requirements for jewellery listings, aiming to improve product accuracy, enhance customer search visibility and reduce returns. The announcement, published on Seller Central, applies to all new listings created from August 2025 onward and introduces stricter classification and material guidelines. Existing listings are not immediately affected but sellers are strongly advised to update their catalogue to meet the latest standards.
New classification now mandatory
Sellers must now categorise each jewellery product as either fine or fashion using the jewellery material categorization attribute. This field helps Amazon determine the correct product type and present relevant options while listing. Any new listing submitted without this classification will be automatically suppressed until the information is added. Amazon says the move is intended to streamline the listing workflow and make product data more consistent across the marketplace.
The update affects new and existing listings differently:
New listings
1.All new jewellery ASINs must have the fine or fashion classification set.
2.If the new attribute is not populated, the listing will be suppressed until it is updated.
3.New pearl listings must include the full set of required pearl attributes.
Existing listings
Existing jewellery ASINs that did not have this classification before 31 August 2025 will not be automatically suppressed. However, Amazon is strongly encouraging sellers to update their catalogues to add the new classification and fill in missing pearl or metal attributes so that all products follow the same standard.

Updated pearl attribute requirements
Sellers dealing with pearl jewellery must now provide detailed, industry-standard specifications for all new pearl listings. Required attributes include pearl luster, shape, minimum colour, type, size per pearl and number of pearls. Optional fields include surface blemishes, uniformity and stringing method. By mandating these details, Amazon aims to reduce customer uncertainty and improve the overall buying experience.
Revised metal and material information
Metal-based jewellery must now include two mandatory fields: metal type and metal stamp. Metal weight remains optional but recommended for improving listing accuracy. Amazon has added new validation checks to ensure that sellers enter correct information that meets marketplace standards.
How sellers can comply
To create new listings, sellers must download the updated Amazon template available on the List Your Products help page on Seller Central. This template includes the new fields and validations that are required going forward. For existing listings, sellers should gradually update their catalogue to include the new classification and pearl attributes where applicable.
Additional considerations for sellers
Optimising listings with accurate attributes can also improve product ranking in Amazon search results. Detailed jewellery specifications help Amazon’s algorithm match products to customer search queries more effectively. Sellers in the fine jewellery category should also ensure that their hallmarking and authenticity documents are up to date, as Amazon may request verification under its compliance checks.
Why Amazon is tightening jewellery data
Jewellery is a sensitive category where small differences in material, stone quality or pearl details can significantly change both price and customer expectations. Clear, standardised data helps Amazon:
(i).Show more accurate search and filter results, especially when buyers filter by metal, stone type or pearl size.
(ii).Reduce disputes, returns and negative feedback caused by unclear or misleading product descriptions.
(iii).Align product detail pages with legal and quality standards for jewellery in each marketplace.
The new attribute rules mark a significant shift in how jewellery products are listed on Amazon UK. While only new listings face immediate suppression for missing information, sellers are encouraged to update older listings to maintain accuracy and competitiveness. By following the revised guidelines and ensuring complete, verified data, jewellery sellers can improve customer trust, reduce returns and position their catalogue more effectively in Amazon’s growing marketplace.
