the mark
what 500 means.
500 is 500 parts palladium per 1,000: half palladium, half other metals. it's a recognized hallmarking standard, but far less common than Pd950.
it's a white metal that weighs much less than platinum, which keeps larger pieces light and affordable.
before you trust it
how to check a 500 stamp.
- look for Pd beside 500. a plain 500 with no letters isn't enough to identify the metal.
- for certainty, ask a jeweler or gold buyer for an XRF scan. it reads the metal's composition in seconds without scratching the piece, unlike an acid test.
