How to Tell if Gold is Real?
There are a variety of methods that you can use to tell if the gold you have is real, here are the most popular methods for testing whether your gold is real or fake:
1. Marking Test – Marked with a “K” or “Karat” – Hallmark Test
Most real gold that is on the market is marked with a K or Karat. This is referred to as a hallmark, and most countries mandate that real gold items, such as gold rings, gold coins, gold bars, and basically anything that is gold to be marked with the karat of gold for the item. This hallmark is often very small and it’s either embossed into the gold item that you have or it’s laser etched into your jewelry. You can usually find the hallmark on the inside of your ring, bottom of your necklace, or on the inside portion of your bracelet. You may need a magnifying glass to assist you with reading the karat of gold for your jewelry. If your jewelry is marked with, for example, 10K or 10 Karat, this means that the gold item you have is considered to be real gold. 10k means that your item is 10 parts real gold and 14 parts other metals, making the gold content in your gold item to be 41.67% gold.
2. Gold Magnet Test – How to Tell if Gold is Real with a Magnet?
The easiest method to tell whether you have real gold or fake gold is the magnet test. Real gold is not magnet, so if you hold it up to a magnet, it should not stick to a magnet. If it does stick to a magnet, then it is not real gold and the party that sold you the gold or your significant other who gave you the gold has some serious explaining to do.
3. Water Test – How to Tell if Gold is Real with Water?
Another easy way to test whether your gold is real is to bring a cup or jug and fill it up with water. Drop your gold item into the water. If the item sinks, it’s made from real gold; however, if it floats, your item is not made from real gold because real gold is heavy and should immediately sink when placed in water.
4. Acid Tests – How to Tell if Gold is Real with Acid?
The acid test is a bit invasive and does involve doing some minor damage to your gold item to test whether it’s real. To perform the acid test, an individual must make a small scratch on the gold item. You then process to add a small drop of nitric acid to the item. If the area you dropped nitric acid on turns green, the item you have is not real gold. If the spot turns milky, this means that you’re dealing with sterling silver that’s coated with gold. If nothing happens to the spot, then you have real gold on your hands because acid does not dissolve or discolor gold.
5. Skin Test
This is a test that takes some time to perform. As you wear gold jewelry, you should not notice any discoloration or colors rubbing off on your skin. So, when you take your “gold” jewelry off, you should not notice any sort of discoloration on your skin. If you notice green, black, or yellowish spots on your skin, chances are the gold item or jewelry you’re wearing is not real gold.
6. Magnifying Glass Test – How to Tell if Gold is Real with a Magnifying Glass?
This test is for people who have a little more experience examining gold to determine whether it’s real gold or fake gold. To successfully perform this test, you need to know a few characteristics of gold.
The first characteristic you need to know to perform this test is that gold is inert, meaning it is very unlikely to react with any substances or things naturally found in the envrionment. So, if you’re examining a piece of gold and you notice some forms of discoloration on your gold jewelry, this should be a sign that you’re either dealing with a low quality piece of gold or that the item you have is not made of real gold.
The second characteristic you should know is that gold has a beautiful soft yellow finish that is not very shiny. So, when examining an piece of gold, if you notice that it’s too shiny or has a reddish color, this should tell you that the item you have in your hands is not real gold or has a high content of metals other than gold.
Also, while you have your magnifying glass out, look for markings, such as 10k, 14k, 18k, 20k, 22k, 24k, or 9999. Any of these markings should indicate to you that the item you have is made from real gold. Of course, the gold content is different depending on the karat of gold you’re dealing with.
7. White Vinegar Test – How to Tell if Gold is Real with Vinegar?
The vinegar test is on the simpler side of tests to test whether the gold piece that you have is real. This test is easy to perform. All you need to perform this test is the item you want to test and some white vinegar. Pour the white vinegar into a container or cup, place your gold jewelry in the white vinegar, and allow it to sit in the vinegar for approximately 15 mins to 20 mins. After the time has passed, take out your jewelry and rinse it with some water. If your gold is real, it will shine like the first day that you bought it, however, if it is fake, it will have changed color as it reacted with the acetic acid in the vinegar. That said, we must warn you that this method may destroy your jewelry if it is not real gold, so please proceed with caution. If the item you believe is gold turns out not to be gold expect to become brown or dark green. So, please proceed with caution. We are not liable for any damage to your jewelry. That said, if your gold is real, it will become as shiny as the day you bought it.
8. Ceramic Plate Test
This test may leave some slight marks on the item you’re testing. To perform this test you need a ceramic plate and the item you want to test. Rub the item you want to test across the ceramic paste while applying some pressure to the item you’re testing. If you see gold residue on the ceramic plate, the item you have is real gold. However, if it leaves dark or black marks on the ceramic plate, the item you have is not real gold.
9. Look For Scratches & Discoloration
If you have jewelry and you want to be able to tell whether it is made from pure gold, gold plated, or gold filled, you may be able to do so if it has deep enough scratches on it or discoloration. Fake gold is sometimes gold plated, so if it gets scratched, the scratch may expose the metal underneath the gold plating. Also, if your jewelry gets discolored, this might be a sign that the jewelry you have is not real gold because real gold only reveals real gold when scratched and it almost never becomes discolored.
10. Bite Test
We included the bite test for fun, but if you have 22K or 24K gold, this test might just work. Pure gold is very malleable, so biting it will leave bite marks on the gold that you have. That said, many pieces of gold jewelry with low karats, such as 10K, 14k, and even 18k have other metals mixed into the gold, so this test will most likely not work on them. However, if you have a small bar of pure gold, this test will work if you bit hard enough. Now, we aren’t telling you to go biting all of your gold, but we included this test for fun.
11. Consult Your Local Jeweler
The best way to tell whether or not your gold is real is to take it to your local jewelry store. Jewelry stores have specialized machines that allow them to examine the elements that are present in your jewelry. Some jewelers have specialized equipment that will give them the exact percentage of elements that make the item you’re testing. So, if you’ve tried some of the gold tests that we have included and you’re still unsure what your jewelry or item is made up of, go to your local jewelry store and ask them to take a look at it. An experienced jeweler will immediately be able to spot fake gold.
