Caution: Not everything that shines and has a hallmark is gold!
Example: Here you can see a type of ring, often on offer, made of solid brass with false gold hallmarks 18 ct / 750. This is offered on the street to gullible people as a so-called "find". Our recommendation: never buy so-called gold from unknown suppliers, especially not in public places.
