Another thing to look for is whether or not the marks indicate that the value has either been measured in karats or in millesimal fineness. Any other numbers than those above would indicate that the gold is fake. Not all real gold jewelry has hallmarks—for example, older pieces may have had original markings that have been worn off.
Any gold that is marked less than 10k Anyone who is familiar with the different levels of quality will quickly recognize the following markings:. They all indicate gold plating. In the same order, they mean:. These markings indicate that only a small percentage of gold was used to cover a piece that was made out of some other kind of metal in order to give it the appearance of gold. To give you an idea of how the upper levels of purity stack up next to one another: 24k gold is This test is simple: It involves holding a piece of gold jewelry between your hands for a couple of minutes.
The perspiration from your hands will either react with the metal and change the color of your skin or leave it unaffected. When real gold is in direct contact with your skin there is no discoloration.
If the gold is fake it will cause your skin to turn black, blue, or green at the contact points. One exception to this procedure occurs if you test gold on your skin while wearing a liquid foundation. When gold touches the makeup it will turn your skin black at the points of contact. Removing all makeup before testing makes this test more reliable. Alternatively, makeup can also be used to test for gold authenticity. Put on a liquid foundation and add powder over it.
Once the makeup has dried, press the piece of jewelry against your skin and then run it lightly over your skin where you have the makeup. If the jewelry leaves a black track on the makeup, you probably have real gold. Gold is extremely nonreactive, so real gold jewelry will never discolor your skin.

For better accuracy, buy a powerful neodymium magnet from a home improvement store. Also, some genuine gold items are made with magnetic metals such as iron. Rub the gold on unglazed ceramic to see if it leaves a streak. Drag your item across the plate until you see some fragments coming off the gold.

Another way to do this is by spreading some cosmetic foundation on your skin and dragging the gold across it after it dries. Fake gold usually reacts with the foundation, leaving a green or black streak in it. Method 2. Look for an official number marking on the gold.
