Test With Nitric Acid

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

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.

A Final Word Of Caution

This article only lists five of the easiest methods to test your gold. As said before, a skilled craftsman may be able to replicate most qualities of real gold using other elements, so even if your piece passes a few of these tests, it’s always good to conduct others, just to make sure. The more tests it passes, the more likely it is to be genuine gold.

There are other ways to test your gold, but these usually require special materials or special tools.

And finally, remember, however, that it is always better to have a professional test your gold piece.

Good luck!

Can Real Gold Have No Markings

Does Real Gold Have to Be Stamped? In the U.S., there is a law that mandates that gold jewelry sold by a vendor must be stamped with a marking that indicates the items karat number. The law also states that the real purity of the piece can deviate by up to 0.5 karats from the karat stamp.

Bonus Test: Head To The Jeweler

If you are really unsure if a piece of jewelry you have is real or fake and these tests havent given you a solid answer, you can always go to a trained jeweler, and they can use more professional equipment to inspect the jewelry and give you an answer.

They will likely charge you a fee to do this, so make sure its an item that you really want or need to know the status of.

How to Test for Fake Gold and Silver

Any gold that is marked less than 10k is considered fake.

Anyone who is familiar with the different levels of quality will quickly recognize the following markings:

  • GP
  • Heavy Gold Plated
  • Heavy Gold Electroplated

These markings indicate that only a small percentage of gold was used to cover a piece that was made out of some other kind of metal in order to give it the appearance of gold.

To give you an idea of how the upper levels of purity stack up next to one another: 24k gold is 99.9% pure, while 18k gold is 75% pure. Absolutely 100% pure gold is unheard of, mainly because pure gold is very soft and wouldnt make for a durable piece of jewelry.

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.

How To Check If Gold Is Real: 5 Easy Methods

  • The Smell Test: Ideal for Small Gold Pieces
  • The Magnet Test: Use a Powerful Neodymium Magnet
  • The Lighter Test: Burning to Test Jewelry
  • The Density Test: Use Water to Test Density
  • The Ceramic Test: Unglazed Ceramic Tile
  • Caution

    Keep in mind that these tests cannot replace the opinion of a professional and are not designed to measure the quality or content of gold in a certain piece of jewelry. It is also recommended that you test your gold item using several of the methods presented here, as fake gold items can sometimes replicate several aspects and qualities of real gold.

    Gold chains such as this one are one of the most commonly available types of gold jewelry…and most easily faked.

    What Is Gold Attracted To

    Ordinary magnetic fields dont attract gold, but a massive magnetic field can make this precious metal slightly magnetic. If your pure gold jewelry is magnetic, chances are that it contains a magnetic material, like iron or nickel. Magnetism is one of the simplest ways to tell if your jewelry or coin is pure gold.

    Take A Close Look At The Metal

    There are other visual clues that can help you determine whether a piece of jewelry is real gold.

    Gold-plated pieces are often marked with GP, GF or GEP . Although the plating is gold, the core of the item is base metal and wouldnt be considered real gold.

    Another thing to look out for is discoloration on any part of the metal. Gold is non-reactive, so wont generally discolor over time.

    A good place to look for color changes is at points of wear. These are usually around the edges of rings, pendants or coins, or on the clasps of chains. If the item has been gold plated, this is where the gold will rub away quickest, exposing the different colored metal underneath.

    How To Tell If Gold Is Real: Bonus Tests

    We don’t highly recommend these tests because they don’t give conclusive results. However, they cost nothing and in no way damage your precious gold. So, why not give them a try?

    a) The Sound Test

    Strike the gold piece with a metal object and listen for how it sounds. Gold makes a high-pitched, sonorous sound that rings on for a long time. Other gold-lookalike metals like copper or zinc will create a duller and shorter sound.

    However, you cannot completely rely on the result because the sound of a 24k and 18k article will not be the same, although both are genuine.

    b) The Bite Test

    You can check the authenticity of gold by biting it, which is not reliable but very popular. You must have seen Olympians biting their gold medals. This is done because gold is a very soft metal, so it can be easily bitten and the teeth marks will appear on the surface.

    The purer the piece, the deeper the teeth marks will be. The texture of gold is also much smoother than other metals, such as silver and nickel, making it easier to chew and identify in comparison.

    To Get A Good Bleach Test You May Need To Damage The Jewelry

    A good job of gold plating may test as real gold. The only way to determine if an item is gold-plated is to scratch the surface. The scratch must be deep enough to penetrate any gold-plating and expose the base metal. A scratch this deep may destroy any value in the item before you even get to the bleach test.

    Look For The Gold Hallmark

    Do you see an official number marking on the gold item? In most cases, the gold item will have a stamp , identifying what percentage of gold it consists of.

    If youre not seeing the stamp, look closely at the items clasp or the inner band of a ring, where the hallmark is most commonly stamped. It can usually be found on the surface of gold coins and bullion as well. You may need to use a magnifying glass to identify an older hallmark that has been rubbed clear.

    For older items, however, a hallmark might not be found on the gold item. Sometimes it is completely worn off. In the U.S., hallmarking wasnt even common until the 1950s and in other countries it wasnt a requirement until much later than that. In addition, some counterfeit items will include a marking that is made to look authentic. So a professional appraisal is still recommended before selling or gifting the item.

    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.

    How Do Jewelers Test Gold And Why Do You Often Only Get Scrap Value

    Jewelers are shrewd business people. The value of gold fluctuates from day to day. Their ability to accurately assess the value of gold items is essential for them to turn a profit. Their offer to you will be related to the price they can achieve when selling on the item. They use science and experience to test gold.

  • A jeweler will examine your gold trinket using a loupe magnifying glass. I always take a 20 x jeweler’s loupe with me when buying jewelry so that I can do the same. Using a loupe means the fine detail of any hallmarks can be read. The jeweler will check the authenticity of the hallmark and feel the weight of the item.
  • Using acid and a touchstone, they will check the karat value of the metal. The chemical reaction of nitric acid on gold demonstrates the alloy content of the object.
  • If the jeweler is satisfied with the result thus far, he will look at the quality of workmanship and the integrity of the item. If it is badly damaged, or of poor quality, you are unlikely to be offered any more than scrap value.
  • Bars of gold are an investment vehicle by themselves and turning them into jewelry often does not increase their commercial value. The resale value of secondhand gold jewelry depends on supply and demand and there may be little demand for old-fashioned or dated pieces. Unless an item is individually crafted and of exquisite quality, second-hand values are low as the jeweler will simply be selling them on to be melted down into gold ingots for investors.

    Can Vinegar Be Used To Test Gold

    How to Tell Real Gold from Fake

    Vinegar can be used to clean some metals. It is not really a testing fluid, it is more of a cleaning agent. If you rub an object made of pure gold with neat vinegar it will remove marks and leave your jewelry shiny and clean. However, if the metal is not real gold, the acid will cause pitting on the surface and your ring or bracelet will be damaged.

    How To Test Gold With Vinegar

    If you’ve ever wondered whether a gold piece is real gold or some other type of metal, you can find out without taking it to a jeweler or pawn shop. Using equipment and ingredients you already have, you can test the authenticity of gold with a very simple test conducted in your own kitchen.

    Rub the gold piece with the clean wash cloth to remove any dust, dirt or contaminants. If there is any stuck-on dirt or grease, get the wash cloth wet and scrub it off.

    Use the eye dropper to place two or three drops of vinegar onto the gold piece. If the piece is very small or doesn’t lay flat, put the gold into a small bowl so the vinegar can stay in contact with it.

    Observe any changes to the gold piece. Gold is a stable metal and does not react with oxygen corroding. Because it is stable, it will not change colors when exposed to vinegar. If the gold piece changes colors, it is not real gold. Gold plate will turn black when exposed to vinegar.

    Run the gold piece under cool water or spray it with a water bottle to remove the vinegar.

    Rub the gold piece with the clean cloth to dry it.

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

    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

    How To Tell If Gold Jewelry Is Real

    When shopping for gold jewelry, you may come across a gorgeous piece without any proof that its actually real gold. Or, perhaps you just inherited a treasure chest of family heirlooms and theres a pot of gold included. Is it costume jewelry or the real deal? Maybe its gold vermeil, gold-plated or gold filled? Ultimately, how can you tell if something is gold?

    If youve found yourself in a similar situation, youve come to the right place.

    Ideally, every piece of gold jewelry would be stamped with a hallmark to signify its authenticity. Unfortunately, the reality is a tad more complicated. Furthermore, we cant always identify jewelry stamps or understand what they mean. Thankfully, there are several ways to discern whether or not gold jewelry real.

    While it might not be visible to an untrained eye, here are some steps for how to tell if gold jewelry is real, or an imposter.

    Measurements To Keep In Mind

    Garfield Refining

    Gold is sectile, which means it can be cut into pieces and molded into shape with tools you can find in a hardware store. The purity of sectile metals is measured by karats, and one karat is equal to 1/24 parts of gold in a metal fusion, also called an alloy. When gold is designated as 24-karat, that means 24 out of 24 parts of the material is gold, making it 100% pure.

    The millesimal fineness system breaks this down more accurately, as it indicates the exact percentage of gold in an alloy. For example, in a 21-karat gold bar, 21 out of 24 parts are made of actual gold, while the remaining three parts come from other metals. That makes it an 875 in the millesimal system because its 87.5% gold and the highest you can attain is 999 or 99.99% purity.

    Thats everything you need to know about gold properties and measurements. Youre now ready to venture into the different testing methods you can do at home.
