How to Tell if Gold is Real or Fake at Home? Clever and Free Ways to Test Your Gold Coins, Bars and Jewelry (Rings, Necklaces, Chains and More)

Gold is the most well-known and one of the most valuable and sought-after commodities on our planet.

Because of its intrinsic value, shady players like to make their inexpensive, unmarked jewelry look more expensive by making it appear like it’s made of genuine gold.

Of course, it’s either fake gold or no gold at all and in both cases you’ve lost your money and your savings.

To be safe you must know how to correctly identify real from fake gold and my guide below will teach you everything you need to know.

7 Easiest Ways to Tell Whether Gold Is Real or Fake (Tests You Can Do at Home)

---

Here’s how you can test gold at your home to see if the gold object you have are made of real gold or fake.

These 7 easiest and free testing methods work on gold coins, bars, ingots, jewelry, rings, chains, bracelets, pendants, broches…

#1- How to Test Gold at Home With Water? (Gold Float Test)

To test gold at home with water you need to fill a container at least half-full with water or more depending on the size of the gold item you’re testing. You don’t need as much water when you’re testing a gold ring compared to when you’re testing a gold bar.

Real gold is a heavy metal and will not float under any circumstance.

Gently drop your gold item into the water. You’re looking to see whether the item will float or drop dead to the bottom of the container.

You have fake gold if it’s the former, real gold if it’s the latter.

Gold float test can also tell you if your gold is real or fake based on whether it tarnishes or not.

Authentic, 100% (24K) gold will never tarnish or rust.

After your gold item has been in water for a while and you notice it’s starting to tarnish and change color then that’s a clear sign your gold is fake. Or your gold idem could also be alloyed with other harder metals.

Note: don’t do the gold float test with an item that has sentimental value to you (given the risk of permanent tarnishing).

#2- How to Test Gold Authenticity By Looking for a Letter Mark?

It’s easy to test gold authenticity by looking for letter marks engraved on the gold object.

The jewelry item that has the letters GF, GP, GF, GEP stamped on it is not made of real gold. GF stands for “gold filled”, GP stands for “gold plated”, and GEP stands for “gold electroplate”. These marks indicate the jewelry is made of some other metal with a thin gold veneer on top.

While this superficial gold plating may be real, it’s only a small part of a complete product and it’s an insufficient amount of gold for the item to be considered true gold.

#3- How to Test Gold at Home With Magnets?

To test gold at home with magnets you need to put the magnet on the top surface of your gold item and see if the item sticks to it. 100% authentic gold will not magnetize.

Gold is non-magnetic so you can use a strong magnet to see if it attracts the jewelry you’re testing.

I said you need a strong magnet because most kitchen magnets are not powerful enough so you’ll need to go to the hardware store and buy the strongest magnet they have.

Keep in mind you might get a reaction from the jewelry if the gold is blended (alloyed) with a magnetic material such as iron.

Also, the rings and bracelets you’re testing might be made of gold alloyed with stainless steel, and stainless steel isn’t magnetic at all. So you’ll get falsely negative results and be duped by fake gold posing as real stuff.

#4- How to Test Gold at Home by Looking for a Hallmark?

It’s easy to test gold at home by looking for an official stamped hallmark

A gold hallmark is a stamp or engraving on gold jewelry that indicates the purity, value, and other information about the piece. It’s a tiny stamp that shows the gold’s karat weight.

Looking for a hallmark on a gold item is the simplest and the best way to tell if the gold you’re testing or want to purchase is real or not.

Different locations use different measurements. For example, In the U.S., the hallmark number is a fraction of 24. This means pure gold is 24K. And hallmark of 12K, or 12 karat, means that half of the gold item is made of gold (other hallmarks used in the US are 8K, 9K, 10K, 14K, 18K, 20K, and 22K).

Gold Karat	Gold Content
24K	100% gold content
22K	91.67% gold content
20K	83.3% gold content
18K	75% gold content
14K	58.30% gold content
12K	50% gold content
10K	41.7% gold content
9K	37.5% gold content
8K	33.3% gold content

If you’re based in Europe you’ll see a number between .000 and 1.000, with 1.000 being 100 percent gold -pure gold.

All of this info is valid only if the hallmark is present. However, your jewelry or supposed gold bullion does not contain real gold if the hallmark is absent.

Moreover, it’s possible the hallmark has worn away over time, which can happen if the item is in constant contact with skin.

Also, if the jewelry is old, it might be real gold but the item was made before hallmarking became a consistent gold authentication practice.

#5- How to Test Gold’s Density at Home to See if It’s Real or Fake?

The density of gold is approximately 19.3 grams per milliliter (g/mL).

The closer your gold item’s density is to this figure, the more real gold it contains.

To find the density of your gold item, you’ll need a container with markings in milliliters and a scale that measures in grams.

First,  weigh your test item and note its weight in grams. Second, put your container on a flat surface and half-fill it with water. Third, record how full the container is in milliliters.

Fourth, lower your gold item into the container so the water doesn’t splash over the sides. Fifth, write down the new water level.

Sixth, subtract the first measurement from the second to find out how many milliliters of water your item displaced. This gives you the item’s volume.

Now, to find the density of your gold item, divide its volume by its weight. For example, if your item weighs 50 grams and has a volume of 2.5 milliliters, its density will be 50 / 2.5, which is 20 g/mL. Since the density of gold is 19.3 g/mL, the chances are your item is mostly real gold and gold content is really high.

Of course, other metals have a weight similar to gold, so this test is a good guide but not completely foolproof.

#6- How to Test Gold at Home With Nitric Acid? (Gold Scratch Test)

To perform the gold scratch test at home you need to get your gold item (for example, a piece of jewelry, a ring) and find a place where you can make a small scratch. On the inside of a ring or under a clasp is fine.

Create a mark deep enough to scratch through the top layer of gold.

Carefully apply a drop of nitric acid to the mark and see whether it turns milky or green. There will be no reaction if the item you’re testing is made of pure gold or is mostly made of gold.

#7- How to Test Gold at Home With Ceramic Tiles?

Testing gold at home with ceramic tiles is excellent for determining whether the item is made of pure gold, or is just plated with a thin gold veneer.

This test again involves damaging your gold item. Don’t worry, you’ll be able to get definitive results with minimum damage.

Find an unglazed ceramic tile. It must be unglazed as tile glaze affects the results.

Gently rub your gold item against the tile until you see fragments of gold flaking off. There’s a very good chance your item is made of real gold if you notice a golden streak where you rubbed.

Your gold item is made of fake gold if you notice a black mark instead of a golden streak.

I don’t suggest using just one method to test for fake gold jewelry. Instead, combine two or three methods for best and most consistent results.

The methods above work for all kinds of jewelry, including gold chains, rings, bracelets, pendants, broches…

Is it Possible too Recognize a Fake 750 Gold Stamp Just by Looking at it?

It’s not possible to recognize a fake, counterfeit, 750 gold stamp just by looking at it.

Instead, you first need to understand there’s a possibility the stamp is fake. And then you should proceed to use one of the methods I described here to see if your gold item is real or fake.

Can Fake Gold Be Stamped 14k?

Yes, fake gold can be stamped 14k.

A 14k stamp on gold doesn’t necessarily guarantee that the gold is real. It could be counterfeited.

Note: fake gold can be stamped 14K.

But it can also be stamped 24K, 22K, 20K, 18K, 14K, 12K, 10K, 9K and 8K.

If in doubt, test!

How to Tell if 24k Gold is Real?

To tell if 24K gold is real you need to test is at home using one of the gold testing methods I provided in this article.

Go to a professional jeweler to have your 24K-gold item appraised correctly if you’re unsure or if it’s important to you to know the truth.

How to Tell the Difference Between Real Gold and Fake Gold Just by Looking at it?

You can’t tell the difference between real gold and fake gold just by looking at it. That’s impossible.

Instead, you need to use one of the easy ways I provided to check if something’s made of gold or not.

If you can, combine several methods for best results.

Does Real Gold Float or Sink in Water?

Real gold doesn’t float in water. It sinks.

Pure gold is a dense material and doesn’t float in water so any item made of real gold sinks immediately to the bottom of the water container.

Is Real Gold Heavy?

Yes, real gold is heavy because it’s a dense metal. Gold has a density of 19.3 grams per cubic centimeter, which is much higher than most other metals.
Real gold also feel heavier than it looks. For example, a real gold ring should match the weight expected for its size and karat value.

Is it Possible to Test Gold With Makeup?

Yes, it’s possible to test gold with makeup. This gold testing method is unreliable though and that’s why I didn’t include it in the main part of my article.

To test gold with makeup you need to take a small amount of liquid foundation and blend it into your hand. Set with powder, and after it’s dried down, rub your gold item on the area.

It’s real gold if the area turns black. There shouldn’t be residue left from the gold after rubbing your gold item on clean, dry skin that’s free from oils, lotions and makeup.

It isn’t authentic gold if a black or greenish mark appears on clean skin.

Note: Test your gold item with makeup on both clean, dry skin and skin with the liquid foundation to see if there is any difference.

Is it Possible to Test Gold With Bleach at Home?

Yes, it’s possible to test gold with bleach at home. I don’t recommend it though as bleach can permanently damage your gold item.

Drop a small amount of bleach on the surface of your gold item. It’s not authentic if it shows signs of discoloration. Real gold will not change color when exposed to bleach.

Once you’re done with the bleach gold test remember to rinse the tested item thoroughly.

Is it Possible to Test Gold With Lemon Juice at Home?

Yes, it’s possible to test gold with lemon juice at home. I don’t recommend it though as lemon juice is not reliable when testing gold’s authenticity and purity.

You can use lemon juice to test gold because of lemon’s acidic nature. Apply a drop or two to the item and look for changes. Genuine gold won’t react to lemon acid. Fake gold will show signs of corrosion or discoloration.

Keep in mind that lemon juice applied to gold item’s surface can permanently damage your item. So be careful with your valuables, especially if you’re testing a valuable, rare gold coin.

And don’t bother testing silver with lemon juice. Lemon acid is too weak to get conclusive results when testing silver coins, bars and jewelry.

Is it Possible to Test Gold at Home With Baking Soda?

Yes, it’s possible to test gold at home with baking soda. I don’t recommend it though as this testing method is inconsistent and unreliable.

Here’s how you can test gold at home with baking soda:

• Step #1– Purchase baking soda from a grocery store.
• Step #2- Create a paste by mixing a small amount of baking soda with vinegar or water in a small container.
• Step #3- Apply the paste to the gold item’s surface.
• Step #4- Gently rub the paste over that surface area.

The baking soda paste will have no effect on real gold. Gold-plated items will change as their base metal (for example brass) will react with the paste and the entire object will discolor.

Testing gold with baking soda is imperfect and it won’t  detect all types of impurities in gold.

Be careful when testing your gold at home with baking soda.

Baking soda is a mild abrasive but strong enough to permanently scratch and damage your tested object.

There are better and safer methods described in this guide.

Note: don’t bother trying to test platinum with baking soda. Platinum is immune to the effect of baking soda, though prolonged exposure will permanently damage your platinum item.

Is it Possible to Test Gold at Home With Alcohol?

Yes, it’s possible to test gold at home with alcohol. This test isn’t the best though.

You need pure alcohol to test gold purity with it. You can’t, for example, use a bottle of whiskey to test your gold item for authenticity.

Here’s how to test gold at home with alcohol.

• Step #1– Apply a few drops of alcohol to the gold.
• Step #2– Gently rub it in with your finger.
• Step #3– Observe the reaction.

Alcohol won’t affect pure (24k) gold. Gold-plated objects will change color depending on the base metal’s reaction to the alcohol.

Alcohol discolors fake gold.

Is it Possible to Test Gold at Home With a Lighter Flame or Fire?

Yes, it’s possible to test gold at home with a lighter flame or fire. This gold-testing method isn’t reliable though and it’s not the first one you should be trying.

Here’s how to test gold with a lighter. It can be a regular lighter or a kitchen lighter.

Hold your gold object close to the lighter. Don’t let the flame touch your gold item.

Observe the reaction. Gold has a high melting point so authentic gold won’t be affected by the lighter’s flame.

Gold-plated item will be affected by the heat from the lighter and will change either color or shape, or both simultaneously.

Fake gold will also visibly respond when exposed to a lighter flame.

Note: don’t bother trying to test palladium with lighter flame. Palladium doesn’t exhibit a visible color change when heated with a typical lighter flame so it’s difficult to distinguish palladium from other metals.

What is the Fastest and Best Way to Test Gold at Home for Free?

The fastest and best way to test gold at home for free is with water (gold float test).

Simply drop your gold item into a water container and see if it immediately drops to the bottom of the container.

Testing gold with a magnet is the second fastest and best way to test gold at home. It takes only a few seconds provided you own a strong neodymium magnet.

Is it Possible to Test Gold at Home With Toothpaste?

Yes, it is possible to test gold at home with toothpaste.

You can use regular toothpaste to test if gold is real or fake.

Rub a small amount of white toothpaste onto the gold item for about 30 seconds. Rinse off the toothpaste with water.
It’s authentic gold if the gold item remains unchanged. Fake gold exposed to toothpaste usually shows signs of wear or discoloration (a black spot may form).

Testing gold with toothpaste isn’t a perfect method and should be combined with other free home gold test for more conclusive results.

Is it Possible to Test Gold at Home With Vinegar?

Yes, it is possible to test gold at home with vinegar.

Put your gold item into a bowl and add a few drops of vinegar (ideally white vinegar, as it’s most acidic and higher acidity is better for this test).

Real gold is non-reactive and won’t change color when it gets attacked by acid from vinegar.

Fake gold exposed to vinegar turns either black or green.

Vinegar gold testing works best on solid-gold items like raw gold nuggets, gold pieces, gold coins or 24k bullion.

Is it Possible to Test Gold With X-ray Fluorescence (XRF) Test?

Yes, it’s possible to test gold with X-ray fluorescence (XRF) test.

It’s one of the most accurate methods for determining gold purity. An XRF machine uses X-rays to measure the elemental composition of the gold and can accurately discover the percentage of gold in an item.

However, you probably don’t have an XRF machine in your home. Unless you’re a professional jeweler, which is highly unlikely considering that you’re reading my article on the best free ways to check if the gold is real or fake.

Is it Possible to Test Gold With Sound?

Yes, it’s possible to test gold with sound.

To test gold with sound, use the “ping test” where you gently strike the gold piece against another object, like a coin, and listen for a long, high-pitched ringing sound.

When struck, genuine gold vibrates at a specific frequency, creating a clear, ringing sound.

Fake gold produces a dull, short sound due to different metal composition.

Is it Possible to Test Gold With Ice?

Yes, it’s possible to test gold with ice.

To test gold with ice, you can place an ice cube on the gold piece and observe how quickly it melts.

Real gold conducts heat away from the ice relatively slowly and this causes the ice to melt at a moderate pace.

Fake gold melts the ice much faster because it has lower thermal conductivity.

Testing if gold is real with ice isn’t a definitive way to test gold and should be used with caution as other factors like the size of the gold piece and the surrounding temperature affect the result and give false positives.

Is it Possible to Test Gold With an Eraser?

Yes, it’s possible to test gold with an eraser.

To test gold with an eraser use a pencil eraser to lightly rub against a piece of suspected gold jewelry to check for a black mark.

The piece isn’t real gold if a black mark appears on the eraser. It’s because the eraser is picking up the plating material from a fake gold item.

Is it Possible to Test Gold With Multimeter?

Yes, you can test gold with a multimeter. It’s not the most accurate method for determining gold’s purity and is best used as a preliminary check. By measuring the electrical resistance of the gold piece you can get a rough idea of its gold content, as pure gold has a very low resistance compared to other metals mixed with it.

Is White Gold the Same as Gold? Or is White Gold Actually Fake Gold?

White gold isn’t the same as regular gold. It’s also not fake gold.

White gold is an alloy of gold. It’s not found naturally on our planet because the Earth has only pure yellow gold, called 24-carat (K) gold.

White gold is made by adding silvery-white alloy metals, such as silver, zinc, and palladium to yellow gold.

It’s called “white gold” because it is white thanks to the presence of these other metals.
