Gold is the quintessential price of status, power, immortality and also wealth, often minimal to royalty.

You are watching: How to tell if gold is real with a lighter

Accounts different on when the an initial gold mines to be dug and also operated. Part say the all started in 3,100 BCE v the old Egyptians. Historical sites like the over-6,000-year-old mines that the Asosa region of Ethiopia and the 5,500-year-old Sakdrisi mine that Georgia put the systematic practice of yellow mining earlier several hundreds of years earlier. Some say that in south Africa there space mines that are even older.

The old Egyptians believed gold was the meat of the sun god Ra. Yellow is taken into consideration luxurious and precious since it is beautiful and also easy come work. That does no tarnish, rust or dissolve (except through aqua regia, the name for nitrohydrochloric acid, which is supplied in one of the tests pointed out below). Gold is hard to extract: right 50 grams come out of a ton of ore. That is also one that the best electrical conductors, which is why it is supplied so greatly inside computers and other technological equipment.


This post discusses numerous tests you can conveniently do at home to help you as soon as you have to know how to call if gold is real.

The rubber stamp Test: Look for Hallmarks

A piece of yellow jewelry is regularly engraved through a hallmark, which is a stamp that identifies its contents and/or manufacturer. Hallmarks usually show up in one inconspicuous place like the inside of a ring.

The standard purity scales are based top top karats and millesimal fineness. The hallmark test, likewise known together the magnifying glass test, is a an excellent place to start as soon as checking if her gold is real.

Hallmarks include:

Valid purity number under the Karat mechanism (like 8k, 9k, 10k, 14k, 15k, 18k, 20k, 21k, 22k, 23k, and also 24k)Valid purity number under the Millesimal Fineness mechanism (333, 375, 417, 583 or 585, 625, 750, 833, 875, 916, 958 and 999)False purity numbers (anything various other than the above)Manufacturer (like ESPO for Esposito, etc.)

Hallmarks show the gold’s level that purity and manufacturer come lend better credibility come a piece’s authenticity and to make it easier to identify and verify. Due to the fact that anybody can engrave any kind of hallmark castle choose, this level of testing is not 100% foolproof

If the numbers say anything other than the ones stated above, then you have actually fake gold. For example, 800, 925, and 950 execute not describe gold, however to silver. Why would certainly they be put 925 ~ above gold? since this often means the jewelry is gold plated through a sterling silver base.

Another thing to look for is whether or not the marks suggest that the value has either been measured in karats or in millesimal fineness. Any kind of other numbers 보다 those over would show that the yellow is fake.

Not all actual gold jewelry has hallmarks—for example, larger pieces may have had actually original markings that have actually been worn off.

Look because that Letter Markings

Any gold the is marked less than 10k (41.7% purity) is considered fake.

Anyone that is familiar with the various levels of high quality will conveniently recognize the adhering to markings:


You will desire to prevent the over designations if you’re searching for real gold. Castle all show gold plating. In the very same order, they mean:

Gold PlatedGold FilledGold ElectroplatedGold Electro PlatedHeavy yellow PlatedHeavy yellow Electroplated

These markings suggest that only a small percentage of gold was provided to sheathe a item that was made the end of some other kind of metal in bespeak to offer it the illustration of gold.

To give you one idea of how the top levels of purity ridge up alongside one another: 24k yellow is 99.9% pure, when 18k gold is 75% pure. For sure 100% pure gold is unheard of, mainly because pure yellow is an extremely soft and also wouldn’t do for a sturdy piece the jewelry. 

The Skin Test


Look because that Bluish or Greenish color on your Skin

This test is simple: It requires holding a piece of yellow jewelry in between your hands because that a couple of minutes. The perspiration from your hands will either react through the metal and readjust the shade of your skin or leave it unaffected. As soon as real gold is in direct contact with her skin over there is no discoloration. If the gold is fake the will cause your skin to turn black, blue, or environment-friendly at the contact points.

One exemption to this procedure wake up if you test yellow on her skin when wearing a fluid foundation. As soon as gold touch the makeup it will revolve your skin black at the clues of contact. Removing every makeup prior to testing provides this test much more reliable.

Alternatively, assembly can additionally be used to test because that gold authenticity. Placed on a liquid foundation and include powder end it. Once the makeup has actually dried, press the piece of jewelry versus your skin and also then run it lightly over her skin where you have the makeup. If the jewelry leaves a black track on the makeup, girlfriend probably have actually real gold.

Gold is incredibly nonreactive, so genuine gold jewelry will never ever discolor your skin. But using the makeup test is a unique method to additionally check if it’s real. 

If there room discolorations in gold jewelry it method you have actually an alloy where there room other metals mixed in.

The Size and Weight Test

This test works well ~ above coins and bars. Girlfriend can

Compare a item of yellow you want to test v one that is currently known to it is in realUse a collection of calipers and a jeweler’s range or use a Fisch Tester

Gold is denser than most other metals. If you have a piece that look at too big for its load or feels also light because that its size, then you probably have fake gold.

Bullion coins room actual coins make from precious metals, including gold, silver, palladium, or platinum. They serve as collectibles, investments, or together a hedge against inflation.

The Magnet Test

Hold a solid magnet next to a item of gold and watch for a reaction. Gold is not magnetic, therefore there need to not be any kind of attraction to magnets. If over there is, friend most most likely don’t have actually real gold.

However, some of the base metals that have the right to be mixed with gold are likewise non-magnetic so you can get a false read. The check isn’t foolproof so it’s a good idea to perform this in conjunction with another an ext accurate testing method. 

The float Test

Just autumn the piece into a container that water. Yellow is dense. If it no float at every or float over the bottom of the container, you might possibly have actually real gold.

The Ceramic scrape Test


Take one unglazed ceramic bowl or piece of tile and also scrape a piece of gold throughout its surface. Real gold will leave a gold note or trail. Other steels will leaving a black color trail.

The Water test (a.k.a. The thickness Test)

This is done by calculation. Friend need

A scale (to weigh the jewelry)A container the water andA way to measure the level in millimeters (to measure the water levels before and after the jewel goes into the water)

Now execute the calculation: subtract the “before” measurement from the “after” measurement. Then division the load of the jewel by the difference in the water levels.

This provides you the density.

The standard density of real gold is 19.3 grams per milliliter (also created 19.3g/mL). No a the majority of other steels come very close to it. If your calculation provides this figure or something really close to it, friend probably have real gold.

When girlfriend use density to identify gold"s authenticity, you likewise need to save in mind the there deserve to be distinctions in density in between different species of gold.

For example, the purer the gold, the more heavier it will certainly be--and white yellow is heavier 보다 yellow. Therefore, the density of gold between 14k and 22k will be all over between about 12.9 and 17.7 for yellow gold and anywhere between around 14 and 17.8g/mL for white gold.

The acid Tests


Vinegar Test

This test simply requires the a couple of drops that vinegar be applied to the metal, hope in an inconspicuous place.

If the steel is real gold there will be no change. If the metal is fake gold it will readjust color.

The Nitric mountain Test

Gold is a noble metal which means its resistant to corrosion, oxidation and acid. To do this test, obstacle your gold on a black rock to leaving a visible mark. Then use nitric acid to the mark.

The acid will dissolve any base metals that aren"t real gold.

If the mark remains, apply nitrohydrochloric acid, additionally called aqua regia (75% nitric acid and 25% hydrochloric acid) come the mark. This mixture dissolves gold so, if the mark disappears, the yellow is real. 

The machine Tests

Electronic Tester (i.e Sigma Metalytics Machine)

The Sigma Metalytics Precious steel Verifier is calibrated for accuracy on a minute scale, enabling it come distinguish between metals in much less than one second. When this equipment is an excellent for measuring bullion and also coins, Sigma Metalytics proposal the Kee gold Tester for testing jewelry.

This device sends electromagnetic waves right into the item, passing through surface materials like wrapping or plating to check out the resistance of the basic metal. That is meter display is collection to display a details range that resistance that is or is not consistent with the resistance the each metal the maker has to be calibrated to detect.

XRF Spectrometer

This device works by sending out X-rays through the gold and exciting that atoms right into a higher energy state.

When the excited atoms return to normal they offer off radiation. The an equipment monitors and analyzes this, making use of the radiation analysis to determine the material. This method is fast and also accurate. The is specific and far outperforms other approaches while law no damage to the items gift tested.

In fact, none of this methods reasons chemical or mechanically damage, therefore they will not jeopardize the value or integrity of her piece.

The Fail-Safe Test


If you really desire to recognize for sure just how much gold is yes, really in your gold, the most tried-and-true method of finding the end is to take it it to a trustworthy jeweler and also have it experiment there.

Jewelers have a wide array of methods accessible to the public for authentication of yellow content. Of course, nothing to win experience. However those who are trying to pass lesser steels off as real gold having become increasingly innovative in their “craft,” so even the jeweler will more than likely resort to machine verification to do sure.

Most house tests can offer you an idea of even if it is or not your gold is real. If they space all good at mirroring probability, none space 100% conclusive.

The best way to recognize for sure if her gold is genuine is to have an experienced and reputable jeweler advice it because that you.
