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.
