While professional testing is essential for accurate valuation, understanding basic gold purity testing methods can help you prepare for selling and verify that your items are genuine.
Understanding Gold Markings
Most gold jewelry is stamped with a purity mark:
Note: Markings can be faked, so they are a starting point, not proof.
The Magnet Test
Gold is not magnetic. If a piece is strongly attracted to a magnet, it is not pure gold or may have significant non-gold content. However, some non-magnetic metals are used in fake gold, so this test alone is not conclusive.
The Ceramic Test
Dragging unglazed ceramic across gold should leave a gold streak, not a black mark. A black streak suggests the item is not genuine gold. Be careful — this test can scratch delicate pieces.
The Float Test
Real gold is dense and will sink in water. If your item floats or hovers, it may be hollow, plated, or made of lighter metals.
Acid Testing
Gold testing acids are available in kits and are the most reliable home method. The process involves:
**Warning**: Acid testing can damage jewelry. Test in inconspicuous areas or consult a professional.
