Jewelry CAD Approval Checklist Before Sampling

CAD approval should authorize a defined next action from a named digital revision. For an early project, that may be a prototype or physical sample. Record the file or drawing identifier, revision, review date, decision and any condition that must carry into sampling. If the model is approved only for shape while a stone, clasp or engraving remains provisional, write that boundary into the decision instead of allowing the word “approved” to imply more.

A digital model can communicate geometry, component relationships and intended dimensions. It cannot by itself prove how the item feels on the wearer, how a hinge or clasp acts in metal, how the actual finish looks, how securely stones are set or how the completed piece will pass project-specific inspection. Those checks belong to the physical sample and later production-release record.

A perspective render is useful for visual direction, but it may hide the back, underside, internal opening or connection points. Ask for the views needed to understand the complete object: front and back for outline and branding; side views for height, profile and projections; underside or section views where construction, hollow areas, settings or wearer contact need explanation. A paired item should also show how the two pieces relate.

Read the dimensioned information separately from the image scale on a screen. Identify the dimensions that control wearer fit or component compatibility for this style—such as ring sizing method, internal bangle opening, chain length, earring drop, pendant scale or bail-to-chain fit. The buyer marks the intended result; the manufacturer should confirm how the design and production route can achieve it.

The stone plan should identify the intended stone shapes, dimensions, quantities and positions, plus which information is provisional. Review how seats, prongs, bezels, channels or pavé areas relate to the actual stone plan and to surrounding metal. A later stone change can affect the setting geometry, so it should trigger review of the affected model rather than being treated as a simple substitution.

Give components the same attention. Check clasps, hinges, bails, jump rings, posts, chains and moving charms at their attachment and movement points. CAD can show the intended relationship, opening and clearance, but the sample must later confirm physical action and wearer experience. Ask the supplier to identify what will be proven digitally, what will be checked during sample making and what requires inspection on the finished sample.

Ask the manufacturer to review wall and section thickness, support, stone-setting access, casting or printing route, assembly, polishing access and finishing needs for the actual material and design. The buyer can identify delicate-looking areas and the intended visual character, while the technical team proposes suitable geometry for its process. A number copied from another alloy, printer, setting or product category is not a reliable approval rule.

Logo, hallmark direction, engraving and other marks also need a defined location, orientation, artwork version and relationship to the finished surface. Review them in a close view and check that their placement does not conflict with a stone seat, hinge, polishing area or wearer-facing surface. Regulatory marking decisions should be confirmed for the destination market and project rather than inferred from a generic render.

A revision log prevents the buyer, designer and supplier from reviewing different versions. Give each issue one location, requested change, reason, owner and status. When a change affects an adjacent feature—such as a stone dimension changing the seat, or a logo moving into a hollow section—note the dependent review rather than closing only the visible comment.

Return one consolidated comment set where possible. The next model should state which revision it replaces and which comments were implemented, declined or remain open. Final approval should cite the exact files and images reviewed, the approved exceptions and the next work authorized. This record then follows the project into physical sampling.

Zalson Jewelry can begin a development discussion from a sketch, reference image, CAD drawing or physical sample. Send the current product reference, intended dimensions and fit, material and finish direction, stone plan, component requirements, logo or engraving files, quantity context and destination market. Mark confirmed, preferred and open decisions so the technical review can respond to the actual project.

After the CAD decision, carry the named revision and unresolved physical checks into the sample record. The sample can then be compared with the intended views, fit, components, finish and markings before any later production release. The development route, feasibility and commercial terms are confirmed for the project rather than promised by this general checklist.
