A Loose Lab Grown Diamond Stones, Calibrated by Shape lot is controlled before it ships, not after. Six QC stations and one reject rule turn a 500-piece tray from a gamble into a known number. Buyers who skip the stations discover defects at their own desk.
The six QC stations on Loose Lab Grown Diamond Stones, Calibrated by Shape
Station one: casting check for porosity and weight. Station two: stone setting for tightness and alignment. Station three: polish and surface. Station four: plating thickness and colour. Station five: stamp and assay. Station six: final pack and carton count.
| Station | What is checked | Pass rule |
|---|---|---|
| Casting | Porosity, weight | Within 5% of sample |
| Setting | Stone tightness | No wiggle, prong closed |
| Polish | Scratches, surface | No visible scratch |
| Plating | Micron, colour | 0.20 micron min |
| Stamp | Karat, maker mark | Matches approved sample |
| Pack | Count, carton | Piece count matches PO |
Each station logs a pass or reject. A piece that fails station two goes back to the setter, not to the next station. The log travels with the carton.
The QC log is not a suggestion. It is the receipt. Without it, a Loose Lab Grown Diamond Stones, Calibrated by Shape defect claim is a he-said-she-said. With it, the bench knows which station missed the piece.
AQL 1.0 on critical defects is not negotiable on Loose Lab Grown Diamond Stones, Calibrated by Shape. A loose stone in a bridal piece is a chargeback. A scratch is a touch-up. Mixing the two classes lets real defects slip.
Buyers who inspect the carton themselves catch problems in seven days, not seven weeks. Sample 32 pieces on arrival, photograph the tray, and sign the receiving note.
The first article is the piece you approve. Bulk is not a new design; it is 50 copies of that article. Pre-production photos must match the approved piece, not a newer version.
The AQL reject rule for Loose Lab Grown Diamond Stones, Calibrated by Shape
Use two levels. Critical defects — sharp prongs, loose stones, broken solder, wrong karat — sample to AQL 1.0. Finish defects — scratches, plating haze, off-shade stone — sample to AQL 2.5.
On a 500-piece Loose Lab Grown Diamond Stones, Calibrated by Shape lot, inspect 32 pieces. Up to 2 critical defects accepts the lot; 3 or more rejects it and the bench re-runs. Write this in the PO so the rule is decided before the pieces ship.
Class C defects are the quiet ones. A slightly off-shade stone passes the lot but tells you the stone lot is shifting. Log it, mention it on the reorder, and the bench adjusts.

What the buyer sees at QC
A buyer who flies in sees the bench, not a showroom. Ask for the inspection photos before the balance: first article, bench shots, plating gauge reading, carton pack. A factory that sends these without being asked is a factory you can stand behind.
A factory that sends photos only after three emails is a factory that will argue about the claim later.
