Whats The Harm Of Using Fake Gold To Make Jewelry

Easy Continuity Gold Testing In Raw Ore With Multimeter – How to / DIY

Using fake gold in the production of jewelry is often accompanied by some consequences capable of destroying the reputation of the business.

The following are some of the embarrassing things that occur in different processing plants when fake gold is used:

  • Pure Gold Processing plant:
  • Color failure: Gold fakers may be able to achieve the illusion of making a product look like gold by plating it with a similar color. However because no plating material can have the same color endurance qualities as gold. The color begins to peel off after some time revealing the original color of the replacement metals.
  • Not qualified for the edition: Despite efforts by counterfeiters to make fake gold look like the real thing. Fake gold cannot pass the quality standard tests to meet up with production requirements. This will lead to a waste in the capital spent on purchasing the fake raw materials.
  • K gold processing plant: The pure gold processing part of jewelry production is not the only place where problems occur. At the stage of the k gold processing plants, there are also some similar but slightly different problems which may be experienced. These include:
  • Safe Test On How To Tell Real Gold From Fools Gold

    There are a few ways to tell the difference between real gold and fools gold. If you are unsure about whether or not your gold is real, then try these methods.

  • Shape: One of the easiest ways to determine whether or not your gold is real is to look at the shape of the stone itself. Real gold is smooth and rounded while pyrite is generally sharp and has angular edges.
  • Color: When comparing pyrite with true gold, pyrite looks more brassy. It is darker than true gold. Gold will always be a true golden color with hints of yellow. Sometimes, though, true gold may have a white-ish yellow color.
  • Check for grooves: The face of pyrite will always have grooves, or striations, along the face of the stone. Gold has no grooves.
  • Weight: Gold weighs more than fools gold. In fact, real gold weighs around two to three times more than pyrite.
  • Testing Gold With Vinegar

    There are plenty of metals and minerals that look like gold including iron pyrite , brass, weathered mica, and chalcopyrite. You dont want to trot into town to show off a gold nugget only to have someone tell you it is iron pyrite or a piece of weathered mica!

    Fortunately, there are several easy techniques to check if gold is real. In this post, Ill be explaining how to tell if gold is real with white vinegar. It is one of the best tests for checking if an object is gold because most people already have white vinegar in their homes.

    What Does Gold Look Like In Ore

    The color of pure Gold is bright golden yellow, but the greater the silver content, the whiter its color is. Much of the gold mined is actually from gold ore rather then actual Gold specimens. The ore is often brown, iron-stained rock or massive white Quartz, and usually contains only minute traces of gold.

    Look At Your Gold Giving Your Suspected Gold The Once Over

    A good magnifying glass can often tell you as much about the gold in your jewelry as testing. Spending a little time giving your treasures the once over can often reveal the truth about the piece. There are a few things to look for when examining jewelry for clues about its worth.

    Look at the Finish. Gold is one of the most stable metals on earth. There are only a few other substances that react with gold. Most of these substances dont occur naturally, so gold rarely shows any discoloration or chemical change.

    Examine your jewelry carefully using a magnifying glass. Look for any discoloration or change in the surface of the suspected gold. Color changes usually point to gold plating or gold mixed with other metals to form a cheaper alloy.

    Look for the Markings. Gold Markings or hallmarks are engravings that jewelry manufacturers include on many higher-quality jewelry pieces. Typically, these hallmarks can tell you who made the jewelry and the purity of the gold.

    On rings, you can find the hallmarks on the inside of the ring. On necklaces and bracelets, these marks are near the clasp. Some stamps may indicate that the item is not pure gold. Some manufacturers use the following markings.

    • HGP Heavy or Hard Gold Plate
    • GF Gold Filled
    • .925 Sterling Silver
    • 1/20 1/20 gold

    Numbers stamps such as 800, 925, or 950 indicate that the item is silver rather than gold

    Advanced Fake Gold Detection Techniques

  • Melting and Sampling spectrum detection: This is a more vigorous test, but is worth the effort and slight cost. Melting and sampling spectrum detection takes advantage of a thermo-analytical technique known as Differential Scanning Calorimetry. A sample of the gold to be analyzed is placed in a Differential Scanning Calorimeter alongside a reference gold sample. The same temperature intensity is applied both to the sample and the reference gold material. The difference in the amount of heat needed to increase the temperature of the sample as compared to the reference is recorded. It is this heat difference that helps to analyze how different or similar a piece of gold is from the original. Fake gold is easily detected with this technique as it will have widely varying heat properties from real gold.
  • Metallographic Analysis: This technique has wide usage and can be found in literature where it has been used for detection of fake gold and silver coins. The results can similarly be applied for the detection of fake gold in jewelry production. Metallographic analysis applies the principles of metallography in the identification of fake gold. This often involves microscopy. Optical microscopy or scanning electron microscopy with energy-dispersive x-ray analysis are two types of microscopy often employed. Since the properties of real gold are already known to experts. A comparison of the sample properties with the expected ones will reveal the originality or otherwise.
  • What Is White Vinegar


    White vinegar is an acidic solution that is made from a combination of acetic acid and water . It is a versatile solution with antibacterial and antifungal properties, that can be used for many different tasks. Although it is a mildly corrosive liquid, it will not harm gold in any way, which makes it the perfect solution for testing if a sample is real gold. You can purchase white vinegar from your local supermarket or hardware store.

    How To Identify Gold

    Avoiding fake gold products may seem very difficult due to the advanced technology being used by counterfeiters. There are however ways known to experts about how to identify fake gold and stay away from it. These include basic methods such as:

  • Contrast Color: This is one of the easiest ways to spot fake gold. In chapter one above, the various types of gold and their respective colors are listed. A close visual inspection will help to identify gold that differs from its specified composition based on the color.
  • Acid Test: This is a simple test that capitalizes on the reaction of gold with acid to prove its originality. All you have to do is make a slight scratch on the surface and add a small drop of trioxo nitrate acid . If the gold does not react with the acid, this is a proof that were dealing with real gold. However if a green or milky coloration is observed, this indicates either fake gold or a gold-over sterling silver product.
  • Cross Section Check: Real pure gold should be continuous. No matter how skilled a counterfeiter is, they can only plate the surface of fake gold with color. This means that by cutting the gold at different positions and breaking it up. Irregularities discovered after a careful look at the cross section will indicate fake gold. Observing various colors or layers of different material after breaking up the gold is a red alert that youre dealing with a fake product.

    How Is Gold Checked For Purity

    ByJoseph Castropublished 30 April 13

    The value of gold is based on the karat system, which is a 24-point scale signifying the percentage of gold a piece of metal contains.

    So, if gold jewelry is 14K, it is 14 out of 24 parts gold, or 58.33 percent gold.

    The acid test is the cheapest method used to check gold. Simple acid test kits typically come with a black touchstone and several acid solutions, which are marked for different karats.

    Experts start by scratching the touchstone using the gold that needs to be tested, leaving a streak on the stone. If the questionable gold is purportedly 14K, they will then make a parallel control streak using a piece of gold that is already known to be 14K.

    Finally, they’ll put a drop of the acid solution on both streaks and compare the ensuing chemical reactions.

    Jewelers may also use electronic gold testers to figure out the quality of a piece of gold. Using a specific liquid or gel, they first create a circuit between the device’s probe and the gold.

    The device then tests the gold’s electrical conductivity this property not only tells the jeweler if the material is actually gold, but also its purity. Electronic gold testers are fairly accurate when used properly .

    The most accurate tests use X-ray fluorescence spectrometers . These machines, which can cost thousands of dollars, send X-rays through the tested item.

    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.

    Another way to test your gold at home is to use a liquid foundation. It may not be as reliable as other sources when it comes to testing your gold but it is good enough to know if the gold is real or fake. Pour some of the liquid foundations on your hand, blend it in your skin and let it dry. Take your gold and rub it on the area where you have applied the foundation. If that area turns black or rubbing the gold leaves a black mark behind then it is evident that the gold is pure. But if rubbing the gold does not affect the foundation applied area, we are sorry to tell you that the gold is not real.

    Test Ductility And Sectility

    If the potential gold in your rock is in large enough pieces one of the easiest and most telling methods to test for gold is checking how ductile it is. Real gold is much softer and more malleable than pyrite or other possible minerals like chalcopyrite or biotite.

    This test is pretty simple. Find a decent sized chunk of the gold and see if you can dent or bend it with your fingernail. If it yields to your fingernail then it is almost certainly gold. The other potential minerals are much harder and more rigid and wont deform by you just pressing into it with your fingernail.

    Similarly, real gold also displays a high amount of sectility. If youre like me and had never heard that word before, that means it is easily cut! If you can find a sufficiently large piece of the gold in your rock , take a steel razor blade or very sharp knife and attempt to cut into it. If the blade slices through then you have found gold! If not, its more likely that youre looking at pyrite or some other mineral.

    How Did Fools Gold Come About

    Not all miners struck it rich though. Many miners believed they found true gold, when in reality they found an abundance of iron pyrite, a mineral that upon initial visual inspection looks like real gold. The name fools gold was coined by prospectors and gold-buyers who were given this look-alike shiny mineral who believed they found real gold. Knowing how to tell real gold from fools gold was crucial in assessing the true value.

    Perform A Streak Test

    Streak tests are another common method used in mineral identification. When rubbed against a streak plate minerals will leave a distinct color streak behind which can aid in the identification process. Gold leaves a distinct yellow streak, whereas pyrite leaves a rather ugly greenish-black streak.

    To perform the streak tests youll need a piece of unglazed ceramic tile, such as the back of a piece of bathroom tile. Its important that the ceramic is not glazed because it needs to be rough and abrasive enough to wear away the mineral being tested.

    Just like you did for the hardness test, youll need to find an edge or point of your rock where the gold youre testing sticks out enough to be able to rub it on the streak plate. Unlike the hardness test its okay if you rub some of the matrix rock along the streak plate as well. Quartz and pyrite are a little harder than the ceramic and might scratch and gouge it, so you can effectively push the rock into the plate to get the gold in contact with it.

    Rub the rock along the streak plate for an inch or two and look at the color of the streak. If it leaves a really nice yellow-gold streak then youre in business youve likely found real gold! If the streak is any other color particularly the dark green-black that pyrite leaves then youve found pyrite or some other mineral.
