Overview

Amazon is rolling out a new set of mandatory data fields for every jewellery listing created after the upcoming compliance deadline. The changes require sellers to classify each piece as “fine” or “fashion” and to provide detailed material attributes; listings that omit these fields will be hidden from search results until corrected. Sellers who rely on Amazon’s marketplace for jewellery sales need to adjust their upload processes immediately to avoid loss of visibility and sales.

Key Points

• Binary jewellery classification — Every new jewellery product must be tagged as either “fine” or “fashion” using the new jewellery_material_categorisation attribute; a missing tag triggers full suppression of the listing.
• Six pearl‑specific fields — Pearl items now need luster, shape, minimum colour, type, size per pearl, and total number of pearls entered, mirroring industry grading standards.
• Metal data requirement — Any piece containing metal must include both the primary metal type (e.g., gold, silver, platinum) and the exact hallmark or stamp such as “925” or “14K”.
• Automated backend validation — Amazon’s system will run real‑time checks on new uploads; listings that fail validation will not appear in browse or search pages.
• Existing listings not auto‑suppressed — Products already live before the deadline remain visible, but they may lose ranking if they lack the new attributes because the algorithm favours complete data.
• Optional enrichment fields — For pearls, stringing method, surface blemishes, and uniformity remain optional but can improve filtered search performance when filled.

How the New Jewellery Classification System Works

1. Select classification — When creating a new listing, the seller chooses “fine” or “fashion” from the jewellery_material_categorisation dropdown. Example: A 14‑karat gold necklace is marked as “fine,” while a costume beaded bracelet is marked as “fashion.”
2. Populate material attributes — Based on the chosen classification, Amazon automatically displays the relevant attribute set. For “fine” items, fields for metal type, stamp, and optional weight appear; for “fashion” items, fabric or synthetic material fields are shown.
