Gold 585 and 750: what the hallmarks mean

Marks such as 585 and 750 indicate the gold content of an alloy. 585 commonly means 58.5% gold, while 750 commonly means 75%. The mark helps with initial identification, but it is not enough for a final valuation.
What should be checked with the mark
Inspection considers condition, net weight, stones, other metals, and whether the mark is consistent with the item. A stamp can be worn, unclear, or require confirmation.
Why one number is not enough
Value does not come from 585 or 750 alone. Weight and alloy testing are also needed. Craftsmanship or collectible interest may matter for some items in addition to metal content.
FAQs
- Is 750 always better than 585?
- 750 contains a higher proportion of gold. That does not mean every 750 item has a higher total value because weight, condition, and form also matter.
- Can I rely on the stamp?
- The stamp is an initial clue. A complete inspection is safer, especially when the mark is worn or the item has an unusual construction.
- How does purity affect the offer?
- Purity affects the amount of pure gold in the item. The offer also depends on net weight and current market conditions.
