By the time a silver shipment reaches your shop, the supplier's photos have done their job and the reality is in your hands. Most quality problems in wholesale silver are not dramatic defects; they are small inconsistencies that add up to returns, warranty claims, and a customer who does not come back. A ten-minute inspection on the receiving end catches almost all of them, and it costs nothing. Here is the routine we recommend every buyer run on a new supplier's first order.

Start with the stamp

Every piece of 925 sterling silver should carry a stamp reading "925" or "S925," usually on the inside of a band, the back of a pendant, or the clasp of a chain. Run a finger along the spot with a loupe. A missing stamp is not always a fatal defect, but it is a warning sign that the factory cut corners on finishing. Also check that the stamp is legible and not an afterthought; a deep, clean stamp indicates the piece was made on proper tooling. US FTC and UK hallmarking rules spell out exactly what must be stamped, and a legible 925 mark is the baseline. If half the box is unstamped, reject or negotiate.

The magnet test

Sterling silver is not magnetic, but many base metals used as cheap substitutes (some steels, ferrous alloys) are. Hold a small neodymium magnet to each piece. If it sticks firmly, the piece is not sterling. This catches the rare supplier who dresses brass or steel as 925. It will not catch silver-plated brass, which is non-magnetic, so the magnet test is a baseline, not a full answer. Pair it with the stamp check.

Inspect the solder joints

Weak solder is where silver jewelry breaks. Look at the joins: where a pendant bail meets the basket, where a clasp ring meets the chain, where an earring post meets the stud. The solder should be smooth, flush, and match the surrounding metal. A visible bead, a crack line, or a joint that looks thinner than the metal around it will fail in customer use. Run a light finger along the joint; a rough edge feels like a defect waiting to happen. This is the single most predictive inspection for future returns.

Check plating coverage

Rhodium or gold plating should cover the whole piece, including the back and the inside of bands. Turn each piece over. A bright front with a dull gray back means the plating was sprayed, not dipped, and will wear through within months. Look at the edges; thin plating shows there first. On chains, run your thumb along every link; the plating should be even, not thicker on one side. Our silver finishes and plating quality guide covers the thickness standards.

Test stone security

For any silver piece with stones, gently nudge each stone with a wooden stick or a fingernail. A loose stone wobbles. On prong-set pieces, look through a loupe at every prong: each should be closed over the stone's girdle, not standing up like a claw that missed. On pavé pieces, run a finger across the top; you should not feel a prong catching. A single loose stone on the sample means the whole parcel will have more.

Clasps and earring backs

Open and close every clasp twenty times. A box clasp should snap shut with a firm click and stay closed when you tug lightly. A lobster claw should spring shut cleanly. Earring backs should grip the post snugly, not spin off with a light touch. These are the components customers touch first, and a sticky clasp on the first try-on loses the sale immediately.

Weight and feel

Compare the piece to a known-good 925 piece you already carry. Silver has a certain density; a piece that feels suspiciously light for its size may be hollow or made of a lighter alloy. Chains especially: a proper silver chain has a satisfying weight in the hand. A "flimsy" feel is a real quality signal, not just a subjective one.

Document everything

Before you sign off the shipment, photograph any defective pieces and send the photos to your supplier within seven days. Most reputable factories will replace defects on the first order without argument, but only if you raise it promptly. Keep a receiving log: date, PO number, defect count, photos. This log becomes your negotiating leverage on reorders and your proof if a dispute escalates. Our import disputes guide walks through the escalation path.

What to do on reorders

Once a supplier passes the receiving inspection twice, you can reduce the check to a spot sample rather than opening every piece. But never stop sampling: factories change, plating lines drift, and a supplier you trusted for a year can slip. A 10% spot check on every reorder catches drift before it reaches your customers.

Ten minutes per box, a loupe, a magnet, and a wooden stick. That routine separates a silver program that earns repeat customers from one that quietly bleeds margin through warranty returns. Make it part of receiving, not an afterthought.
