We often think that just because our jewellery is expensive, it must be real then. Many have fall victim to imitation gold, believing that what they bought was the real deal. If you never found yourself wondering if your gold is fake and then come to see afterward that the gold on your jewellery is fading, then well done to you. Men’s and ladies watches are known to fake, as well as rings, but with a simple DIY test, you will soon no if it’s the real deal.
All precious metals can be tested by using acid, although it will harm the fake material, it won’t cause any damage to genuine materials.
- Make a small mark on the piece of gold to penetrate the exterior.
- Drop a small amount of liquid nitric acid on the scratch and wait for a chemical reaction.
Fake jewellery will turn green once the acid touches the surface, whereas real gold will have no chemical reaction to nitric acid. However, Gold-over-sterling silver will become milky in appearance.
Fake gold will cause skin discolouration if you hold it in your hand for a few minutes, the perspiration will create a small chemical reaction with the gold. If your skin changes black or green, it’s a clear sign that it’s counterfeit gold. Genuine gold will have no reaction to skin whatsoever.
A magnetic test is the most convenient and transportable test for genuine gold, since the magnet can be kept in your pocket. Imitation gold and other alloys will attract the magnet. Just as coins can appear to be gold, when in fact the exterior is only gold in appearance. The magnet would reveal the underlying metal. Genuine gold will not attract a magnet.
Any size piece of genuine gold will immediately sink to the bottom of any liquid. Imitation gold floats or hovers above the bottom of the container. Also, real gold will not rust or discolour when wet.
Jewellers can determine the contents of any gold piece of jewellery. Certified consultants will conduct tests that reveal the genuine gold weight and purity. But whether it’s real or fake, we can’t help but be mesmerised at the beauty of each piece of jewellery we come across.
