How to request custom designs in nickel-free 925 silver?

A buyer should request the precise alloy composition for every relevant component, including the base metal, solder, findings, and plating layer. The term nickel-free is not established merely because an item is marked 925: sterling silver contains at least 92.5% silver, while the remaining portion can vary by formulation. Ask for a material declaration and identify which finished components are covered. For regulated markets, request an appropriate nickel-release report from a competent test provider rather than relying only on a supplier statement. The report should identify the submitted sample, test method, result, and applicable market requirement.

The brief should state the required silver standard, the restriction on intentional nickel use, and the components covered by that restriction. Specify whether the requirement applies to the main body, solder, posts, clasps, chains, jump rings, and any decorative inserts. Also record the desired hardness, color, finish, and manufacturing process because alloy changes can affect forming, polishing, soldering, and durability. A vague request for hypoallergenic silver can create conflicting interpretations; a component-by-component specification is more useful for sourcing and quality approval.

Yes. A surface layer can affect the material that contacts skin, but wear, friction, sweat, polishing, and production variation may expose underlying components over time. Plating should therefore be treated as one part of the compliance assessment, not as a substitute for controlling the base alloy and solder. The design brief should identify the plating material, finish, thickness requirement if applicable, areas of direct contact, and expected wear conditions. Nickel-release assessment should use the finished article or a representative production sample when the market requirement calls for it.

For many European-market articles intended for direct and prolonged skin contact, REACH Annex XVII sets a nickel-release limit of 0.5 micrograms per square centimetre per week; articles inserted into pierced parts have a lower limit of 0.2 micrograms per square centimetre per week. EN 1811 is commonly associated with nickel-release testing, while EN 12472 can be used to simulate wear and corrosion before testing where relevant. The buyer should confirm the destination market, product category, laboratory scope, sample condition, and report requirements before approving a method. Testing should be planned around representative finished samples, not only raw material declarations.

CAD files should define geometry, dimensions, tolerances, contact surfaces, stone settings, joints, thicknesses, and areas requiring polishing or plating. Add a separate manufacturing specification that identifies the approved silver standard, restricted nickel use, component materials, solder expectations, surface finish, and inspection points. Marking a single note such as nickel-free on the drawing may not control findings or assembled parts. Include revision numbers and approval status so the prototype, golden sample, and bulk-production reference remain traceable. A manufacturer can then assess mold complexity, finishing access, and potential material substitutions before quotation.

Cost is influenced by silver weight, design volume, mold or tooling work, stone or component count, soldering complexity, polishing access, plating, packaging, testing, and the requested order quantity. Nickel-free requirements may also add documentation or independent testing costs when a destination market requires evidence. MOQ is commonly affected by mold economics, production scheduling, component sourcing, and the amount of customization rather than by the alloy statement alone. Ask for separate sample, tooling, testing, unit-price, and bulk-order assumptions. Confirm lead time after the design, material specification, sample approval, and testing scope are fixed.
