How can I tell if jewelry is real gold?
Check hallmarks, documentation, and the seller. For valuable pieces or uncertainty, professional testing is the most reliable route.
Does gold stick to a magnet?
Gold is not ferromagnetic, but a magnet test is only a clue because many other metals also do not react strongly.
What does 750 mean on jewelry?
750 indicates 750 parts gold per 1,000 and is associated with 18k gold. The stamp alone does not prove authenticity.
What is the most reliable way to verify a piece?
Professional analysis, together with reliable documentation and hallmarks, offers more confidence than isolated home tests.
