How to check it yourself
- Examine the stamp under a 10× loupe — genuine marks are crisp and evenly struck, not doubled or smeared.
- Confirm the mark reads Pd950 or an equivalent such as PD950.
- Weigh the piece and estimate its volume — the density should land near 12 g/cm³ for this alloy.
- Photograph it in the Jewelry Identifier app to read the metal, hallmark, and any gemstones from the image.
- For a binding result, have an assay office or gemological lab run an XRF purity test.

FAQ
- Q. Is Pd950 the same as PD950?
- A. Yes. Pd950, PD950, Pd all denote the same material — 95.0% palladium. Different markets and eras stamp it differently, but the purity is identical.
- Q. How do I confirm a Pd950 stamp is genuine?
- A. Look at the mark under 10× magnification for crisp, even strikes, cross-check the weight-to-volume ratio against the expected density (12 g/cm³ for this alloy), scan it with the Jewelry Identifier app, and — when it matters — have an XRF test done by an assay office or gemological lab.
