Neodymium magnets are very strong and can helpto test the authenticity of gold and silver bars, coins,bullion, orjewelry. However, it is important to note that this method is not foolproof.
How It Works
Gold and silver are not consideredferromagnetic due to theirlack of iron, nickel, andcobalt.With that said, ifa neodymium magnet is attracted to the gold or silver, that means that it contains trances of other metals and is not pure.
However, thistest is not entirely foolproof.For example, if the item ismade from aluminum or copper, itwill also not be attracted to a neodymium magnet.
Additionally, some fake jewelry may be made of ferromagnetic materials and still pass the magnet test if the magnet is not strong enough to detect the material. Therefore, it is important to use a strong neodymium magnet when testing jewelry for authenticity.
Gold and Magnets
Gold, despite being classified as a metal, does not possess inherent magnetic properties like Iron, Cobalt, and Nickel do. Pure gold is not magnetic. However, under certain circ*mstances, gold can exhibit temporary magnetic behavior when exposed to a strong magnetic field. This temporary magnetism is similar to how annealed iron and steel can be magnetized when placed near a permanent magnet.
It is important to note that gold, in its pure form, will not magnetize or attract to a magnet. Nevertheless, certain factors can influence the magnetism of gold. For instance, when gold is alloyed with other metals like iron, zinc, nickel, copper, cadmium, aluminum, silver, platinum, and palladium, it may acquire magnetic properties. The percentage of these metals in the alloy can determine the extent to which gold may be affected magnetically.
Magnet Recommendations
As mentioned above, it's important to use a strong neodymium magnet when testing gold or silver for purity.
We recommend using a strong neodymium disc magnet like the one below to test the authenticity of your gold and silver.

FAQs
How It Works. Gold and silver are not considered ferromagnetic due to their lack of iron, nickel, and cobalt. With that said, if a neodymium magnet is attracted to the gold or silver, that means that it contains trances of other metals and is not pure. However, this test is not entirely foolproof.
What is the best magnet to test gold and silver? ›
While the magnetism in gold and silver cannot be detected with weaker magnets like ferrites or ceramic magnets, its weak magnetic force can be detected with a rare earth magnet like the N52 Neodymium magnet.
Will a magnet pick up gold and silver? ›
Although silver and gold are not magnetic, this doesn't mean nonmagnetic items are always real precious metals. Plenty of items like watches or pieces of jewelry could be made with non-magnetic material like copper or plastic. Some metals look like silver but are not magnetic like aluminum, pewter, and zinc.
How can I test my gold and silver at home? ›
Magnet Test
Take a strong magnet, such as a rare-earth neodymium magnet, and hold it at a 45° angle. Place the gold or silver coin or piece of jewelry at the top of the magnet. It should slide down the magnet's surface slowly to the bottom if it has a high purity level.
How can you tell if something is real gold without a test? ›
Gently drop your gold item into the water. Real gold is a heavy metal and will not float, so if your gold item floats you know it is not real gold. Also, if you notice rust or tarnishing on the item after being in water, this is also a sign it is not real gold since gold doesn't rust or tarnish.
What is the quick test for silver? ›
Silver tarnishes quickly, turning black, when in contact with bleach. A small spot of bleach can therefore be used to identify silver. The tarnish can easily be polished away, and silver items should leave the cloth slightly blackened by the tarnish being removed.
How to test silver with vinegar? ›
To test silver with vinegar, mix equal parts of white vinegar and baking soda in a bowl and stir until the baking soda is dissolved. Then, dip a clean cloth or cotton swab into the mixture and apply it to the silver object. If the object is real silver, the mixture will cause a reaction that will bubble and fizz.
Can you pick up 925 silver with a magnet? ›
Silver is not magnetic, not even with the strongest magnet. However, silver is diamagnetic. If you hold a silver coin at 45 degrees a suitable magnet will slide down it slowly. This is because the moving magnet sets up an 'electrical field'* that slows its fall.
What looks like gold but is magnetic? ›
First off, if your "pure gold" is magnetic, then there is iron inside (or maybe nickel). In fact, this is one way to tell if jewelry is actually gold. If it's not attracted to a magnet then there is no iron - but it still might not be gold. Scammers have been known to coat lead, copper, and aluminum.
Will a magnet pick up white gold? ›
Although white gold often includes nickel, a magnetic material, the amount used is generally too small to result in a significant magnetic effect. So, in most cases, white gold is not magnetic!
With that said, if a neodymium magnet is attracted to the gold or silver, that means that it contains trances of other metals and is not pure. However, this test is not entirely foolproof. For example, if the item is made from aluminum or copper, it will also not be attracted to a neodymium magnet.
Does fake silver stick to a magnet? ›
Silver isn't noticeably magnetic. In fact, only iron, nickel, cobalt, gadolinium, neodymium and samarium are magnetic in our everyday lives. Knowing that silver isn't magnetic is useful since it can help you spot fake silver.
Can 14K gold be slightly magnetic? ›
In summary, a 14k solid gold necklace should not be noticeably attracted to a magnet, and if it is, it could be a sign that the necklace is not genuine gold or that its composition is different from what's claimed. However, for a definitive assessment, professional testing is advised.
Will 14K gold stick to a magnet? ›
Gold, in its pure form, is not magnetic. It is known as a diamagnetic material because it has a weak repulsive force toward magnets.
What is the best way to test gold? ›
The Water or Float Test
You can test gold at home by using a water method known as the "density test" or "specific gravity test." Since gold is denser than most other metals, it will sink when submerged in water.

Purity Markings
The most common hallmark is meant to tell you an item's precious metal purity. The first thing you want to look for is the shape of the stamp. A rectangular shape with the corners shaved off will tell you immediately that the item is gold. An oval stamp would indicate the item is silver.
