7 ways to know if something is gold or imitation
Although the easiest way may be to consult a jeweler, you may not have time to go to a jewelry store or you just don’t feel like going, so fortunately there are some methods that will help you to detect and discover for yourself if an object is gold in a matter of seconds.
Below we explain the most effective methods to check if something is gold that anyone can carry out without complication before visiting a jeweler to give you his verdict.
Take a visual exam
You can start checking if your gold is real by doing a first eye inspection. You should focus on finding the characteristic signs that differentiate gold from a vulgar forgery.
The objective of this visual exam is to find a label that indicates the purity or carats of the jewel in question. A magnifying glass or magnifying glass will help you in this work.
Although it is possible that if the piece is very old it no longer has any visible sign or mark. And it is also possible that some pieces include brands that ensure their authenticity, even if they are fakes. That is why it is important to conduct a deeper examination to see if the object is gold.
Look at the discoloration of the object
To check if something is gold we can look at the areas that have lost their color. These discolored parts are usually located at the edges, since they are the parts most exposed to friction or friction.
If you see that there are parts that have stopped being golden, it is more than likely that your jewel has simply been gold plated and that it is not real gold.
Consider running the bite test
It is the most typical and perhaps the one we have all seen in thousands of movies.
To check if your object is of real gold by the bite test, you must do the following:
- Bite the object with moderate pressure.
- Examine the marks. Examine the marks. Normally, real gold will reveal the notches of your teeth, and its depth indicates its purity.
Although it is not the most recommended way to check if it is gold, since in addition to the possible damages, there are other materials that, when biting them, leave similar marks, so you can believe that your object is gold when in fact it simply has been bathed in gold, it may serve you in some circumstance where you do not mind altering the object.
Take the exam with magnets
Using images to check if an object is real gold can be as easy as it is effective.
Using images to check if an object is real gold can be as easy as it is effective. Perhaps a small magnet is not effective, but a more powerful one can be very useful in determining if your gold is real. You can find magnets with greater force in some pieces of hardware, so you can reuse some component of some old equipment or ask in a store specialized in computer products.
Gold is not a magnetic material, so if you bring the magnet closer to your jewel, it stays stuck, you may find yourself facing an object that is not real gold.
Try the density test
The density of 24K pure gold is around 19.3g / ml, which makes it denser than most other metals. Few metals are denser than gold.
Measuring the density of your objects can help you determine if your gold is real. The rule is simple: the higher the density, the greater its purity.
For more reliable results, make sure the object has no gemstone or anything added.
To check the density of your object, the first thing you should do is weigh it. Normally, you can easily do it without any cost in any jewelry. You will need to know the weight in grams.
Put some water in a bowl. If possible, use a container with measuring marks. It is advisable to measure millimeters.
The amount of water does not matter, but do not fill it to the brim since the logical thing is that the liquid overflows when the gold is introduced into it.
You must introduce the object into the water and pay attention to the difference in millimeters between before and after submerging the jewel.
The formula is very simple:
Density = Mass / Volume Shifted
If the result is close to 19 g / ml it means that you are facing real gold.
Let’s look at it with an example:
If we have an object that weighs about 40 grams and displaces 3 millimeters of water, using the formula we have to:
40/3 = 13.33
That is, the density is 13.33. Now, we must take into account the different purity that gold can have:
|Quilates||Composición||% de oro|
|24k||24 gold parts||99.9%|
|22k||22 gold parts, 2 parts of another *||91.6%|
|18k||18 gold parts, 6 other parts *||75%|
|14k||14 gold parts, 10 other parts *||58.3%|
|10k||10 gold parts, 14 parts of another *||41,%|
* Alloy metals such as copper, nickel or silver
The different purity of gold has a different g / ml ratio.
- 14K: from 12.9 to 14.6 g / ml
- 18K yellow: 15.2 to 15.9 g / ml
- 18K white: from 14.7 to 16.9 g / ml
- 22K: from 17.7 to 17.8 g / ml
Carry out the ceramic plate test
If you are looking for a quick way to check if something is gold, you can do it using a ceramic plate. It is very important that the dish you use is not glazed.
If rubbing your jewel on the plate appears black lines, it means that your object is not gold. However, if these lines are golden it means that you are facing genuine gold.
Complete the test with nitric acid
This is an extraordinary way to check if your jewel is gold. Perhaps the most difficult part of this method is to get nitric acid. In addition, the risks involved in handling it may be more advisable to request this test from a jeweler.
To perform this check we must place the object to be examined in a small stainless steel container. Add a drop of nitric acid to the object and wait to see how it reacts:
- If it turns green, it means that the object is either made of another metal that is not gold, or simply gold plated.
- If the reaction is golden, it means that the item is brass and gold plated.
- If, on the other hand, the color it takes is white, it can mean that your jewel is sterling silver and gold plated.
- If there is no reaction, chances are you are facing real gold.
What can you do if you are in possession of a piece of authentic gold?
If I am facing a piece of real gold I must tell you that it is possible that you have something with a high value in your hands. However, you should know if it is authentic gold and how many carats is its purity, which will be what truly determines its market value.
Selling gold is currently one of the star investments since it is a very desired object whose value does not seem to fall.
Depending on its size and its purity, selling gold is a very profitable operation with the guarantee of being something with a demand always ready to pay for it.
