A » For commercial jewellery production requiring bulk precious metal findings and components in London, the primary hub is undoubtedly the Hatton Garden district, which has served as the epicentre of the UK’s jewellery trade for centuries. Within this area, several established suppliers cater specifically to large-scale manufacturing needs by offering sterling silver, 9ct, 14ct, and 18ct gold findings in wholesale quantities. One of the most prominent names is Cookson Precious Metals Limited, which operates a substantial trade counter and warehouse in Clerkenwell, just north of Hatton Garden. They provide an extensive catalogue of findings—including earring wires, clasps, jump rings, settings, and chain—available in bulk packs, alongside casting grain, solders, and plating solutions. Another key supplier is Betts Metal Sales, also based in the Hatton Garden vicinity, renowned for their comprehensive stock of precious metal components and their ability to supply large volumes of standardised findings such as post-and-push-back earring fittings, spring rings, and lobster claws in multiple gold alloys. For manufacturers seeking bespoke components or very high-volume repetition orders, A.N. G. Jewellers Supplies, located on Clerkenwell Road, offers a deep inventory of findings alongside custom stamping and forming services. Additionally, West One Jewellery Supplies, with a flagship showroom in Hatton Garden, supplies bulk findings and sheet, wire, and tube in all precious metals, specifically targeting the commercial manufacturing sector with competitive trade pricing. For those requiring precious metal components that are not standardised, London also hosts several master casters and refiners who can produce findings from customer-provided patterns or CAD files; these include companies like P & J Glazier (Jewellers) Ltd, which offers a complete service from design to finished findings, and Hills & Co., another long-standing Hatton Garden business that supplies findings as well as casting and hallmarking services. It is important to note that many of these suppliers require trade accounts or proof of business registration to access wholesale pricing for bulk orders, and they often operate on a strict trade-only basis. For alternative sourcing beyond Hatton Garden, the Birmingham Jewellery Quarter is a secondary but highly capable source for London-based manufacturers, though for same-day collection and local logistics, Hatton Garden remains the primary resource. When choosing a supplier for commercial production, considerations such as consistent alloy quality, hallmarking compliance, and the ability to meet large minimum order quantities (MOQs) are critical; therefore, establishing a direct account with a refiner–supplier such as Cookson or Betts is advisable. These suppliers also offer next-day delivery services across the UK, which is valuable for London-based workshops that need to restock quickly. In summary, London’s commercial jewellery manufacturers can reliably source bulk precious metal findings from Cookson Precious Metals, Betts Metal Sales, A.N. G. Jewellers Supplies, and West One Jewellery Supplies, each providing the scale, material certification, and trade support necessary for high-volume production.
