Professional and Old-Fashioned Tests to Check Purity of Silver and Gold
The discoloration of the skin happens on wearing fake gold and this is not any myth. A simple test is to hold gold for a few minutes in your hand. There will be perspiration and the chemical reaction will give skin a green or black color if it is not genuine gold. Genuine gold does not react. There are certified tests conducted to verify its purity and weight.
Genuine silver and gold jewelry have karat marking that will be stamped representing purity. Just get familiarized with the US and European markings.
Gold is a noble metal and it will not discolor or corrode with certain acids, but the base metals may. The kits of the acid test are available online and they also come in kits with a vial and scale for density testing. Remember that an acid test may mar a product if it is not pure 24 karat gold.
For a float test, you just need a cup of water. Any genuine gold piece will sink immediately to the bottom, while the imitations float. Secondly, real gold does not rust when wet.
Sonogram or X-ray

-Second, the sound test can be known by tapping your finger on the silver or gold coin or tapping it with another coin. The pure silver and gold coins have a high tone resonating for a few moments, while plated or fake products sound is dull and becomes silent immediately.
-Finally, the bite test. Biting gold leaves a physical impression of your bite as pure gold is soft. However, avoid this test as there is the risk of hurting your teeth. Besides, in case it is a bar, your teeth may not reach owing to the base metal slug in the center.

There are plenty of dealers like silver ring wholesale who get gold directly from the refinery or mint and these are tested professionally for purity.
