The Magnifying Glass Test

The Magnifying Glass Test is the first home test for gold you can perform if you want to determine the authenticity of your gold product. This test is straightforward since it requires only your gold bullion or your gold jewelry and a magnifying glass.

Through this test, you must carefully inspect your gold item with the magnifying glass to find a few essential visual clues about it. These include:

If your gold piece didnt pass the Magnifying Glass Test, you can be sure that you dont have a pure gold item. But, if you want to find out its fineness, you can proceed to further testing.

For the next testing method, you may still need your magnifying glass. Since your item, especially if its jewelry, could also contain several other gold hallmarks besides the purity marking, you should examine it further to test its authenticity.

Performing A Density Test

  • 1Weigh your piece of gold on a scale. If you have a decent kitchen scale, place the gold on it. Otherwise, jewelers and appraisers often can do it for you for free. Call around to different jewelry or appraisal stores to see which ones offer this service. Make sure you get the weight in grams rather than ounces.XResearch source
  • You need the weight in grams to use in a calculation later. If the weight is in ounces, you wont get an accurate result.
  • 2Fill a graduated cylinder halfway full with water. Choose a cylinder that is big enough to hold the gold. It needs to have measurement markings in milliliters or cubic centimeters . If you dont have a regular graduated cylinder, you could try using a kitchen measuring cup.XResearch source
  • Vials with frequent millimeter markings on the side are useful for getting a more accurate measurement during the test.
  • The amount of water you use doesnt matter that much as long as you leave plenty of space for the gold. If you fill the vial to the top, dropping the gold into it causes the water to spill.
  • 3Read the starting water level in the cylinder. Look at the markings on the cylinder, then record the water level. This measurement is very important for the test, so write it down. Make sure you have the vial on a flat, level surface in order to get as accurate a reading as possible.XResearch source
  • Write the second measurement down on a piece of paper. Note that this is the second measurement, not the initial one.

    Ways Of Telling If Gold Necklace Is Real

    Gold is a very dense, corrosion-resistant metal, which makes it a great jewelry material. It is also soft and therefore can be shaped to make beautiful jewelry. Gold comes in a variety of shades, from pale yellow to deep rose.

    Even though gold is a relatively soft metal, it is still durable enough to be used as a jewelry material. Gold can be plated with rhodium which makes the jewelry more durable and prevents tarnish. On the other hand, if your gold necklace or bracelet has been worn for a long time or has been exposed to chemicals such as chlorine or hair spray, you may need to have it re-plated, so it will not tarnish.Do Metal Detectors Detect Gold and Silver?


    Gold is often mixed with other metals to make it stronger and easier to shape. The most common metal used with gold is copper, but silver and nickel are also good choices. The purity of gold means that all the other metals and elements are removed from the metal before it is sold as jewelry.

    Pure gold is 24 karats 22 karats means that 91.7 percent of the element by mass is pure gold 18 karats means 75 percent pure gold 14 karats means 58.3 percent 10 karat means 41.7 percent pure gold.

    There are several ways experts use in identifying if a gold necklace is fake or real. We would be looking at 4 of the basic methods, which include:

    A Question Of Tarnishing: Does Real Gold Tarnish

    How Do You Test Gold Using Vinegar? Multiple Methods For Checking If It ...

    We all know that sterling silver tarnishes. Is the same true of real gold? If we are talking solid, 24k gold, the answer is no. Gold itself does not tarnish. However, keep in mind that the majority of gold jewelry is not solid gold because of durability issues.

    If you want gold jewelry that is not going to tarnish, you need to stick with solid gold that is a higher karat quality. 18k gold and 14k gold is not likely to tarnish. If you go below that level, say 10k gold, you might notice some tarnishing.

    If you have a piece of gold jewelry that has tarnished, keep in mind that that doesnt mean the gold is fake. Follow some of those above tests to see if it is real.

    If youve got real gold that has tarnished, you can clean it using some mild soap and water. Dry the jewelry with a soft cloth- dont use anything abrasive! Similar to when you clean sterling silver, you have to be careful to not scratch the metal.

    Heat Your Gold Jewelry With The Lighter

    Once everything is ready, begin the test.

    Apply the flame to the jewelry for about a minute or 60 seconds. Watch it closely for any changes in color.

    Fake gold will get darker, while pure gold will do the opposite: it will get brighter the hotter it gets.

    The brighter your jewelry gets, you can rest assured you have real gold.

    What Are Your Options

    If you decide that the bleach test is not a real option, what else can you do? There are many other less destructive ways to test a piece of jewelry for gold content. Most of these do not require any damage to the item. In some cases, these other tests and clues will give you much more information than a home bleach test.

    Xrf Thermo Scientific Gold Test

    Its the most expensive precious metal tester, yet the most accurate and nondestructive one. This gold analyzer uses X-ray fluorescence spectrometers to test the gold piece. The device sends X-rays through the sample and makes atoms get momentarily excited, moving them into a higher energy state. When the atoms return to their ground state, they release radiation which is detected and read by the machine. The machine returns the exact Karat or metal composition of the tested piece. It also comes with a unique AuDIT gold-plating detection technology which alerts you if the tested item is gold plated.

    How Can You Tell If Something Is Gold Plated

    How to Test Gold Using Specific Gravity.

    The most trustworthy method to test if something is gold plated or solid gold is to have an acid test done it. For the acid test, take a small piece of jewelry, or using a small needle scratch a tiny part in your gold, take a dropper given in the acid kit, fill it with acid. Now use this dropper to inject that scratch with a small drop of acid. The scratched part is likely to change its color in response to the reaction with the acid. Look carefully which color has it changed to and match it with the color card given in the acid kit. This will not only tell you if the gold was fake or real but will also help you in identifying the actual metal it is. To test your gold at home with this method you will need to get an acid testing kit that is easily available at jewelry stores and even online. The acid test is also used to determine the Karat of the gold. If you decide to use this method, please read the instruction given in the kit carefully before you begin the procedure.

    The Ceramic Test: Unglazed Ceramic Tile

    This test is actually quite simple and takes only a second to do. To do it, you’ll need an unglazed piece of ceramic, such as the unglazed bottom of a plate. If the ceramic is glazed, this method will not work.

    To do this, simply pick your gold piece and carefully drag it across the unglazed ceramic surface so that it creates a streak on it. A black or otherwise dark-colored streak means your piece is not made of gold, while a gold streak indicates that it is genuine.

    Again, be careful when doing this, and bear in mind that your item may end up scratched. Usually, a little polish is enough to do away with the marks, but if done improperly, the piece may require repair. Always use common sense when conducting these tests.


    Try other tests first, and use this streak test only if you are still unsure whether your gold jewelry is made of actual gold. This test, when done improperly, can scratch or otherwise damage your gold piece. When in doubt, seek the opinion of a professional jeweler.

    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.

    Beware Today Counterfeit Gold Is Everywhere

Other times, you might have an unmarked piece of gold. To understand its actual value, you need to authenticate it.

    These factors are why its crucial for you to know how to tell if your gold is real. It will help you protect your investments, accurately appraise your belongings, and make sure you get the exact gold you are paying for.

    Is Real Silver Magnetic

    Silver possesses a number of remarkable properties that make it valuable in a variety of industrial and high-tech applications. Silver is dense, ductile, highly reflective, and one of the most highly conductive metals in existence. However, silver is not magnetic.

    Silvers lack of magnetic attraction gives you a quick way to test any given silver product to see if it contains foreign metals such nickel, iron, or cobalt. These cheaper metals will respond to magnets.

    Fake silver products rarely appear for sale anywhere, if no other reason than theres far greater financial incentive for forgers to tamper with gold bars or numismatic coins. Some fake silver novelty items from China may occasionally show up at flea markets or on eBay.

    Density Check Via Water Displacement

    This test method has been around for a very long time: the Greek mathematician and physicist Archimedes developed it in the 3rd century BC. The density of the bar or coin in question is determined by immersing it and measuring the resulting displacement of water. Archimedes discovered that every metal has a specific weight that of 24 carat gold with a fineness of 999.9/1000 is 19.3 g/cm3. A great advantage of this method is that, in addition to authenticity, the fineness of gold can also be reliably determined. However, extreme accuracy is required: even the water temperature must be exactly 20° Celsius, because it is only then that the density of the water is exactly 1 g/cm3. In addition, the test object must also be completely smooth all around, as even the smallest water bubbles can influence the measurement result. Detailed instructions on how to conduct the water displacement test to produce a reliable result can be found on the Internet.
