How To Tell If Gold Is Real With Acid
A few drops of nitric acid can help you determine whether gold is real or not. However, this is a dangerous chemical, so be very careful when doing this test.
Wear goggles and gloves. Do the test in a well-ventilated area. Finally, be aware that this test can damage jewelry if you dont know what youre doing, so consider having a professional jeweler handle the test for you.
Does A Karat Stamp Guarantee That A Piece Of Jewelry Is Solid Gold
In short, no, a stamp is not a guarantee that a piece is really gold.
For instance, gold-plated jewelry can have karat stamps, but they will indicate the purity of the gold plating, not of the entire piece. For example, the stamp 14K GP means that the item is gold plated and the plating is 14-karat gold, but the piece is actually made of another metal.
So, the lesson is that you should always pay attention to whether there are other letters stamped besides the karat number.
Can Vinegar Be Used To Test Gold
Vinegar can be used to clean some metals. It is not really a testing fluid, it is more of a cleaning agent. If you rub an object made of pure gold with neat vinegar it will remove marks and leave your jewelry shiny and clean. However, if the metal is not real gold, the acid will cause pitting on the surface and your ring or bracelet will be damaged.

The Magnet Test: Use A Powerful Neodymium Magnet
For this test, you’ll need a rare earth magnet.
Rare earth magnets aren’t the common type of magnets you can find on your fridge, for example. They are made of special alloys, which give them incredible power. For this test, a neodymium magnet is recommended, as they are readily available online, very affordable, and among the most powerful rare earth magnets.
Caution
Neodymium magnets that are larger than just a few centimeters are quite powerful, and if a body part gets pinched between a magnet and a highly magnetic metal part or another magnet, serious injury can occur. Handle the magnet with care.
Now, to test your jewelry, simply touch it with the magnet. Pure gold will not be attracted to the magnet. If the jewelry gets attracted to the magnet , then at least part of it is not gold. Gold chains and collars commonly have a “clasp” mechanism of some sort, and you may find that only the clasp bit sticks to the magnet. This is because there is a spring inside the clasp mechanism, and gold doesn’t make good springs.
Remember, however, that even if your jewelry piece does not get attracted to the magnet, there’s still a chance it may not be gold. This is because other, non-magnetic elements can be used in making fake gold. Most commonly, though, fake gold is composed using metals that are at least somewhat magnetic, and a strong rare earth magnet should be able to exert some attraction over these.
How To Test If Gold Is Real
A true symbol of high status, success, and prosperity, gold is a luxurious, highly desired precious metal. However, even if you own a stamped gold piece, its hallmark isnt a guarantee of its real gold content. This article explores the best testing methods on how to perform a proper gold test. Remember that you can always get a free top-notch appraisal from our expert NYC Bullion team.

The Water Test: Measure The Density
The density test involves how much a gold bar or coin weighs compared to how much water it displaces. If the item is genuine, it will be heavier than water, and the increase in weight is proportionate to the purity. If there are any other additives in your gold like copper, then it will be much lighter than it should be.
You will need a kitchen scale, a container with measurement markings, and water for this test. Follow these steps:
The result should be close to 19.3 g/mL, which is golds standard density. In comparison, copper has only 8.96 g/mL of density. The density of 18k and 14k gold items are 16.5 g/mL and 14.0 g/mL, respectively. The densities of alloys vary depending on how much gold is present.
A Final Word Of Caution
This article only lists five of the easiest methods to test your gold. As said before, a skilled craftsman may be able to replicate most qualities of real gold using other elements, so even if your piece passes a few of these tests, it’s always good to conduct others, just to make sure. The more tests it passes, the more likely it is to be genuine gold.
There are other ways to test your gold, but these usually require special materials or special tools.
And finally, remember, however, that it is always better to have a professional test your gold piece.
Good luck!

How To Tell If Gold Is Real: What Are Fake Gold Items Made Of
To understand the properties of counterfeits, you should know the composition of genuine items. The unit for measuring authenticity is Karat and you will find various denominations from 24 to 8 karat.
A 24k gold article is pure as it has 99.9% gold element in its composition. On the contrary, a 14k item contains only 58.3% gold and the rest is a metal alloy featuring two or multiple metal items .
Gold bullion coins and bars
Your gold items like jewelry or coins will have a metal alloy because of the soft nature of 24k gold. Its too flexible to hold a firm shape.
Remember that a jewelry piece or coin can be genuine without looking like gold. For example, white gold is 75% pure gold and 25% alloy of nickel and zinc. It imitates platinum but is similar to 18k gold.
On the other hand, counterfeit gold articles are not gold at all. They are made of completely different materials and only have a thin gold coating on the exterior. Some common and popular imitation variations are:

White gold is the lustrous white gold alloy. It is made of at least one white metal, besides pure gold. Often, the white metals that are alloyed with pure gold include zinc, palladium, nickel, and/or silver. In other cases, copper could be added to the gold and the rest of the white metals. All the metals added to gold to create the white gold alloy not only result in the yellowish-white gold but also reduce the brittleness of the metal alloy while adding shape and durability to the gold.
But because of the copper and the rest of the metals added to the pure gold, the resultant alloy is not really white but often appears yellowish, with a greyish hue. So, why call it white gold, and where does the lustrous white finish on white gold come from? Well, to create white gold as we know it, the resultant gold alloy is coated in a lustrous white metal from the platinum metal group, called rhodium. In other words, white gold is more like the gold alloy plated in rhodium.
Unfortunately, its not always easy to tell white gold from other lustrous white metals, which is why information on how to tell white gold from other white metals like sterling silver or platinum right from the comfort of your home is quite important.

What If A Gold Piece Doesnt Include A Karat Mark
In some cases, gold pieces wont include stamps or other markings to indicate their karat rating. In the U.S., the National Stamping Act of 1906 requires that jewelry sold by vendors include a stamp with a karat marking, but this isnt the case in all areas of the world. If this is the case with your piece, a jeweler can perform an in-person test to determine its value.
The most commonly used test is with nitric acid, which is a corrosive and colorless mineral acid. This acid reacts with many different materials, including copper-based alloys. When a piece of metal has a high concentration of copper, the reaction between it and the nitric acid is more powerful. Counterfeit gold pieces are generally copper-based, often including materials like tin and copper. Nitric acid also reacts to gold with a low karat rating, although the reaction isnt as strong as it is to copper-based material.
In a nitric acid test, a jeweler places a few drops of the acid on the piece and watches the reaction. With copper, the reaction usually causes the liquid to turn green, give off fumes, and sometimes bubble. This response is known as a hard cupric reaction and indicates that your piece is not real gold. Lower-karat gold pieces may produce a mild cupric reaction, which includes minimal to no fumes, no color change, and little to no bubbling. You may see a small black mark where the acid came into contact with the piece.
Test Gold Using The Magnet Test
One way to test if your gold is real or not is the magnetic test. For this test, you will need a stronger than the usual magnet you have at home. Take your gold that you want to test place it on a wooden surface, Bring the magnet closer to the gold, gradually. If the gold is attracted to the magnet, it is not real gold but if the gold remains indifferent to the magnet then it is in fact real. If the gold you are testing has a clasp, only the clasp may be attracted to the magnet since in some of the jewelry items the clasps are not made of gold.

The Smell Test: Ideal For Small Gold Pieces
While this test is far from being the most reliable way to tell real gold from fake gold, it’s one of the easiest and quickest to do, and will not damage your jewelry.
You know that awful smell your hands get after you hold some coins in it for some time? We’re looking for that smell in this test.
This test can be done in three easy steps:
You see, one cheap metal used in the making of coinage is brass, a mixture of copper and zinc along with other materials. Brass can look like gold, especially if made into an alloy with other metal, to try to approximate gold’s weight and color. However, brass is much more reactive than gold when in contact with salty water and air, it produces the characteristic acidic smell most coins have due to an electrolytic reaction.
As such, if your “gold” jewelry exhibits the same smell, it very likely is not real gold, or at least not pure gold. But even if your gold jewelry passes this test, it can still be fake gold.
