the mark
what 950 means.
950 is 950 parts pure metal per 1,000. for platinum it's the standard used by most fine jewelers, particularly for engagement rings and settings, because platinum is dense, naturally white and very durable.
palladium is platinum's lighter, less expensive cousin. at 950 it looks almost identical, but it weighs roughly half as much for the same size.
the letters matter more than the number. Pt, Plat or Platinum means platinum; Pd or Pall means palladium.
before you trust it
how to check a 950 stamp.
- read the letters beside 950. Pt or Plat means platinum, Pd or Pall means palladium.
- feel the weight. platinum is nearly twice as dense as palladium, so a platinum ring feels noticeably heavier than a palladium one of the same size.
- don't rely on a magnet. most platinum isn't magnetic, but some platinum-cobalt jewelry alloys are slightly magnetic, so a weak pull doesn't prove a fake.
- 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.
