What does a 500 hallmark mean?

The number is parts per thousand
Fineness marks state how many parts in a thousand are the precious metal. 500 is 500 parts in 1,000, so 50% of the weight is palladium and the rest is the alloy that gives the piece its colour and hardness.

Is it real? Three quick checks
- Look for company. A genuine UK hallmark has the fineness number inside a shaped outline, plus a sponsor's mark and an Assay Office mark. A lone number with nothing beside it is a claim, not a hallmark.
- Watch for plating codes. GP, GEP, HGE, RG or a fraction like 1/20 12K mean a thin layer of gold over base metal. These are worth very little as scrap.
- Check with a magnet. Gold, silver and platinum are not magnetic. A pull towards the magnet means a steel or nickel core.
None of these replaces a test. We check every piece with an XRF analyser before we make an offer, so you are paid for what the metal actually is, marked or not.
