Incoming Inspection Checklist for Jewelry, With the Piece in Your Hand

The delivery is open, the packing list has been reconciled, and a silver bracelet is sitting in your palm. From here nothing is administrative. Every remaining question is answered by looking at the piece, turning it, measuring it and working the parts that move. An incoming inspection checklist for jewelry exists so that examination follows the same order every time, rather than following whatever catches your eye first.

Below we run the check in the sequence a bench uses, from the way the piece reads at a glance through to the settings, with the failing result named at each step.

Set the bench before you open a pouch

Inspection quality is decided by the surface you work on. A dark, non-reflective mat, one directional lamp you can tilt the piece into, a magnifier on a stand, a digital scale, a caliper, a ring mandrel and a set of soft tweezers cover almost everything.

Keep the approved reference piece for the model within reach and unopened until you need it. How light, magnification and a reference piece work together is set out in the inspection bench walkthrough. Work one piece at a time and return each to its own pouch before the next comes out.

First pass: the piece as a customer meets it

Hold the piece at arm’s length, front face towards you, under even light. Do not magnify anything yet. This pass answers whether the piece looks like the product you sell.

• Does the shape match the reference piece in outline and proportion?
• Does the colour match, held side by side under the same lamp?
• Does anything sit crooked — a bail leaning, a pendant hanging off centre, a pair of earrings that are not mirror images?
• Does the piece hang or drape the way it should when suspended?

Anything that fails here fails for a customer too, so it needs no further investigation before it goes into the reject pile.

Dimensions and weight

Measure against your specification rather than against the previous delivery. The previous delivery may itself have drifted.

• Overall length and width in mm, taken at the points your spec names.
• Chain length with the clasp closed, laid flat and gently straightened.
• Ring size on a mandrel, not across a caliper.
• Material thickness at the thinnest section, which is usually where a piece will eventually give way.
• Weight in grams, after cleaning, recorded piece by piece rather than as a total.

Metal and marking

Find the stamp before you judge anything else about the metal. It should be where your specification puts it, legible without a loupe struggle, and struck cleanly enough to read in one direction.

• The mark is present on every piece, including components ordered as marked.
• The figures match the alloy ordered.
• The strike has not distorted the surrounding surface or dished the wall behind it.
• Components that were specified as the same alloy as the body actually match it in colour under the lamp.

Surface and finish under raking light

Now tilt the piece into the lamp so the light skims across the surface. Marks invisible under flat light appear immediately at this angle, which is exactly why your acceptance standard has to name the viewing condition it applies.

• The named finish is consistent across the whole visible face, without patches of a different texture.
• Recesses that should read dark are even, and recesses that should be bright are not clouded.
• Edges and high points show the same colour as the flats, with no thin or worn areas.
• No polishing compound remains trapped in corners, under bails or inside links.

Joints, solder seams and load paths

Trace every joint with the magnifier, then test the ones that carry load. Follow the path a wearer’s weight would take through the piece and check each connection along it.

• Jump rings are fully closed, with no gap that a fingernail catches.
• Load-bearing rings specified as soldered are actually soldered rather than closed only.
• Seams are filled and dressed flush, with no proud fillet on a visible face.
• Gentle opposing pressure across a joint produces no movement, flex or sound.

Parts that move

A clasp is the component customers report first, because it is the part they operate every day. Work it repeatedly rather than once, since a mechanism that binds only occasionally is the one that generates returns.

• The clasp opens and closes with one hand and stays closed when the chain is pulled.
• Springs return fully, with no sticking at the end of travel.
• Hinges hold their position and show no side play.
• Earring posts are straight, smooth to the tip, and backs grip without needing force.

How that testing is applied consistently is covered in the guide to clasp and moving-part function tests.

Stones and settings

Check settings last, because handling the piece through the earlier steps will already have loosened anything marginal. Work under magnification with a fine probe rather than a fingertip.

• Every stone is present and seated to the same depth across the piece.
• No stone rocks, clicks or shifts under light probe pressure.
• Prongs and bezel edges are dressed smooth and do not catch on fabric.
• Tables sit level with each other in a row rather than stepping up and down.

The probe technique itself is described in the guide to checking stone setting security, and our quality control and packaging page shows where the same checks sit inside a workshop’s own flow.

Work the list in that order and stop the moment a piece fails a step, because a piece with a loose stone does not need its weight recorded. Send the failures back with the step number and the failing observation attached to each one. A supplier who receives “failed step six, jump ring open at the bail” can act on it the same morning, while a supplier who receives a box and a complaint spends that morning guessing.
