Frequently Asked Questions

How do I weigh my gold correctly?

Use an accurate digital scale with at least 0.1g precision. Weigh only the gold, removing gemstones, chains of other metals, or any non-metallic parts. For complex jewelry, consult a professional.

What do I do if my gold has no karat mark?

If there's no visible mark, you'll need an acid test kit or an electronic gold tester. These methods will allow you to determine the actual purity. Professional jewelers usually offer this service. Aprende más sobre cómo identificar oro auténtico.
