How To Test If Gold Is Real

Don't Miss

Test With Nitric Acid

How to test if your gold is real

Find a place on the jewelry where you can make a small scratch, perhaps under a clasp or on the inside of a ring. Make a mark deep enough to scratch through the top layer of gold. Carefully apply a drop of nitric acid to the mark, and determine if the mark turns green or milky. There will be no reaction if the jewelry is either gold or mostly gold.

Nitric acid is a dangerous chemical, so you should take every precaution when handling it. Wear gloves and goggles, and be sure the room is well-ventilated. Given the potential damage this test does to the jewelry, you may not want to apply it to something of great personal value. At least consider having a professional jeweler do the test for you.

Check Whether It Leaves Behind Marks

Gold is hypoallergenic, so gold jewelry should never stain or irritate your skin. If your jewelry has left behind a mark on your skin, it isnt gold. A black mark usually means its silver. A green mark usually signifies copper.

But strangely enough, gold will leave behind a mark on unglazed ceramic. That means that another way to check whether your gold is real is to scrape it lightly across an unglazed ceramic tile. Make sure that theres no glaze present on the tile, though, as this will affect the result.

The ceramic will lightly scratch your gold, so this approach does cause some damage. Do it with care, though, and it will be so slight as to be barely noticeable.

What youre looking for here is the mark left behind by the item youre testing. If its real gold, the mark will consist of tiny particles of gold. That means it will be the same yellow color as gold. If its black, the item is made of base metal, or a mineral-like iron pyrites .

You can also perform a test using cosmetics. Apply some foundation to your skin and leave it to dry. Then rub the item over the skin covered in the foundation. The foundation contains hard minerals which will scrape away tiny particles of metal. Fake gold will usually leave behind a black mark.

How Is The Purity Of Gold Determined

You have probably heard of the most widely used purity measure for gold, which is karat. When someone refers to a piece of gold jewelry, they indicate its karat rating to show how pure it is. The karat scale goes from zero to 24, so when a piece of gold has one karat, it includes one part real gold, and the other 23 parts are made of different types of metal or alloys. An 18-karat ring would include 18 parts of real gold and six parts of other types of metal.

You can further break down the scale into parts per thousand, or the percentage of real gold to alloy or other metal. Simply divide the number of karats of your gold by 24, and then multiply that number by 100. A 20-karat gold necklace would be 83.3% gold, which youd find by dividing 20 by 24 to get 0.833, and then multiplying that by 100 gives you the percentage. In other words, a 20-karat piece of jewelry has 833 parts of gold for every 1,000 parts.

Test Against A Ceramic Tile

This test involves scratching your gold item however, you should be able to get results with minimum damage. Find or purchase an unglazed ceramic tile. It must be unglazed since tile glaze affects the results. Gently rub your item against the tile until you see fragments of gold flaking off. If it leaves a gold streak, theres a good chance your item is real gold. A black mark indicates the gold is fake.

Test : The Float Test

Life Hack

For jewelry youve got at home you can always do a quick float test to see if it is real or fake! All you need is a cup of water.

Drop the jewelry in the water and see what happens. Real gold will sink, as it is a heavy metal. If the jewelry floats, more than likely, it is not real gold.

If it doesnt immediately sink or does not sink all the way, you may have jewelry that simply has less real gold than you thought it did.

How To Tell If Unmarked Gold Is Real

Gold is the quintessential image of standing, energy, immortality and wealth, typically restricted to royalty.

Accounts differ on when the primary gold mines have been dug and operated. Some say all of it started in 3,100 BCE with the traditional Egyptians. Archaeological websites just like the over-6,000-year-old mines of the Asosa area of Ethiopia and the 5,500-year-old Sakdrisi mine of Georgia put the systematic apply of gold mining again a number of 1000s of years earlier. Some say that in South Africa there are mines which can be even older.

The traditional Egyptians believed gold was the flesh of the solar god Ra. Gold is taken into account luxurious and treasured as a result of its lovely and simple to work. It doesnt tarnish, rust or dissolve . Gold is tough to extract: Barely 50 grams come out of a ton of ore. Additionally it is top-of-the-line electrical conductors, which is why its used so closely inside computer systems and different technological gear.

Perform An Acid Test To Authenticate Gold

This at-home gold test may be difficult since it can be hard to obtain nitric acid and theres always risk involved when bringing any type of acid into your home. If you do perform this task, you should wear a mask since this can be a potential health hazard if not handled properly. If youre uncomfortable with this process, leave it to the professionals!

Many jewelers use the nitric acid method to determine the authenticity of gold jewelry. Drop a small amount of nitric acid onto the piece and look for a reaction.

If the jewelry is gold plated, you may have to make a tiny scratch in the metal to allow the acid to saturate the underlying metal.

If the acid produces a green reaction, the jewelry in question is probably a base metal or gold plated. A white, milky reaction is most likely indicative of gold plating over sterling silver.

What you really want to see is no reaction at allreal gold should not react when it comes in contact with nitric acid.

Can You Bite Down On Real Gold

The answer is Yes, you can bite down on real gold. If youre a sports fanatic then youve probably noticed athletes biting their gold medals on several occasions. This is not a type of game ritual but a test of authenticity and proof that it is possible to bite down on real gold.

As you know, gold in itself is a soft metal. That is why it needs to be mixed with other metal alloys to harden it and make it more durable. On the Mohs scale, real 24K gold has a 2.5 score on the scale. This is opposed to the dental enamel with a slightly higher score. That means that your teeth are the ones capable of scratching gold and not the other way around. As such, you should be able to bite down on real gold without harming your teeth. You may even be able to leave a slight dent on the piece of gold.

The term real gold is, however, relative. As weve mentioned hardening gold, it must be mixed with a certain percentage of metal alloy. The resulting gold alloy is still considered real gold. In the US, gold stops being considered real gold when its 10K gold which contains more metal alloy than actual gold. So, in this case, it may be more difficult to bite down on a 14K gold piece as opposed to a 24K gold piece. Thats because the lower the karat, the less pure the gold and the harder it is.

Ways To Tell If A Ring Is A Real Gold

However, before you take your item in for a professional appraisal, there are some simple methods for discovering whether your gold item is real or fake.

Real Gold Does Not React To Oil

If your finger or other area of the skin turns green or black after wearing the item, it is not pure gold. Gold does not react to the oils in our skin, but silver and copper both can leave behind green or black marks. However, some gold items that are made up of a mix of gold and other items, up to 14 karats, can also leave behind a mark on the skin.

The Stamp Test: Look For Hallmarks

6 Ways to Tell if Gold Is Real

A piece of gold jewelry is often engraved with a hallmark, which is a stamp that identifies its content and/or manufacturer. Hallmarks usually appear in an inconspicuous place like the inside of a ring.

The standard purity scales are based upon karats and millesimal fineness. The hallmark test, also known as the magnifying glass test, is a good place to start when checking if your gold is real.

Hallmarks include:

  • Valid purity numbers under the Karat system
  • Valid purity numbers under the Millesimal Fineness system
  • False purity numbers
  • Manufacturer

Hallmarks show the golds level of purity and manufacturer to lend greater credibility to a pieces authenticity and to make it easier to identify and verify. Since anybody can engrave any hallmark they choose, this level of testing is not 100% foolproof

If the numbers say anything other than the ones mentioned above, then you have fake gold. For example, 800, 925, and 950 do not refer to gold, but to silver. Why would they be put 925 on gold? Because this often means the jewelry is gold plated with a sterling silver base.

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 hallmarksfor example, older pieces may have had original markings that have been worn off.

Test It With Your Skin

Perhaps the easiest method on this list, the skin test measures the level of impurity in a gold item by merely holding the object in your hand. Just make sure the area of skin youre testing against is clean of anything that might interfere with the reaction, such as lotion. Because of real golds properties, it shouldnt result in any discoloration or staining of your skin the way brass might leave a greenish tint.

To run the test, hold the item in your hand for a few minutes. Base metals will react to the sweat on your skin and create a chemical reaction. As a result, your skin should turn green or black depending on the metal or alloy its reacting to. If there are no marks on your hand, then you can trust that the item in question is real gold.

Liquid foundation presents an alternative way to test whether something is gold. After applying a thin layer to your skin and letting it dry, gently rub the gold against it. If that results in a line or black streak, then the gold is likely genuine.

Testing Gold With Household Items

  • 1Drop the gold into a jug of water to see if it sinks. Get a container big enough to hold both the water and the gold youd like to test. The water temperature you use doesnt really matter, so lukewarm water is fine. Real gold is a dense metal, so it falls directly to the bottom of the jug. Imitation gold is much lighter and floats.XResearch source
  • Real gold also doesnt rust or tarnish when wet, so if you see a discoloration, you probably have plated gold.
  • 2Put a few drops of vinegar on the gold. Set your jewelry or gold piece onto a flat surface. Use an eyedropper to apply a bit of vinegar and let it sit for about 15 minutes. Real gold wont change color, but fake gold will.XResearch source
  • You can also submerge the gold in a glass container with vinegar for 15 minutes. This is a slightly riskier method because vinegar might damage semi-precious stones on gold jewelry.
  • 3Find any noticeable discolorations where the gold has worn away. Gold is pretty soft for a metal, so plated gold often rubs away over time. The best places to check are around the edges of jewelry and coins. These spots often rub up against your skin and clothing throughout the day. If you see a different metal underneath the gold, you know your item is plated and not considered real gold.XResearch source
  • For example, a silver coloring might indicate silver or titanium. A red coloring could mean copper or brass.

    Gold Testing: Ways To Know If Your Jewelry Is The Real Deal

    Is Your Gold Real? How To Test 10K Gold with Acid – Real Results!

    You cannot tell the difference between real and fake gold just by at first glance. That is why it is easy for dishonest sellers to dupe people into buying fake items. Fortunately, there are ways to know if your jewelry is the real deal or merely fools gold:

    Look for marks

    Manufacturers put stamps in the clasps of bracelets, necklaces and rings to let you know its purity. If you do not find one in your jewelry, chances are it may not be genuine. Older jewelries are the exception, however, as it was only recently that the method was applied. Suspicious marks, dents, shapes and discolorations around the edges are also some of the telltale signs of fake gold.

    Check the statistics

    People have standards on the size and weight of real gold depending on the karat. Research the standard dimensions of pure gold thoroughly. Using calipers, measure the diameter, thickness, size and weight of your jewelry. If it does not match the usual dimensions of its kind, then it is most probably gold clad or one that is mixed with other metals. Drop your jewelry in the water real gold usually sinks.

    Drop nitric acid

    Real gold does not react to nitric acid. Try the acid test if physical examination does not work. Scratch lightly on the jewelrys surface and apply a small amount of nitric acid on it using a dropper. If the surface turns green, your jewelry might be gold clad. A milky substance appears if your gold contains sterling.

    Apply cosmetics

    Use a magnet
