TRI GEM JEWELRY Content Team·2026-03-01T16:00:00+00:00·Updated 2026-11-05T10:03:01.873000+00:00 ![Material inspection station for silver alloy checks](https://wp.trigemjewelry.com/images/xrf-lab.jpg) ## Hallmarks and what they certify A 925 stamp or hallmark declares alloy content; on finished jewelry it is normally applied during production and repeated on a clasp or inner band. It is a declaration, not a test report. Buyers comparing offers should confirm who applies the mark and where it sits, since polishing and plating can soften or cover shallow stamps. ## Tolerances and how they are checked Silver content is checked on the alloy before casting and, where a report is required, on a finished sample. Weight tolerance per piece and dimensional tolerance matter as much as the silver percentage for repeat orders. Ask the supplier to state tolerance in the spec sheet; without it, two matching lots can differ enough to show in a retail assortment. ## Comparing suppliers on the same basis The practical comparison is: confirmed alloy, confirmed weight, plating, findings and testing method. A supplier who states all five is easier to hold to a repeat order than one who quotes only a price. Keep the approved specification attached to the purchase order so every repeat run is checked against the same document.
