How to check real gold at home


It is well known that when everyone went to two types: type a real original type made ​​of pure gold and its price is high, which is another type of ormolu, which is not made ​​in any material or component precious value.

And of course, not one of us wishes to purchase at the price of gold ormolu real so we must very careful when you buy a piece of gold.


How to check the authenticity of the gold at home ?

Gold – a precious metal , which due to its softness is usually combined with other metals ( alloys prepared , of which give jewelry ) . Content of pure gold in a gold alloy sample is measured . For example, in a gold alloy 750 contains 75 % pure gold and the remaining 25 % – ligature and impurities.

Despite the fact that the circulation of precious metals is strictly controlled by the state pursuant to the precious metals and stones , gold jewelry is often counterfeited. For example, underestimate the amount of pure gold, gold or replaced by other cheaper metals yellow. Therefore, at the time of purchase , especially in unfamiliar places or other people , it is important to know at least a few simple ways to check it gold or not. Different ways to check its cost and degree of difficulty , depending on how accurate you want results , and what is the nature of the test “sample” .

Precede the tests to check for gold or fake

In nature there are substitutes for gold is very close to him physical properties. For example , pyrite ( mineral golden color with a metallic luster , represents an iron compound with sulfur , sulfur or iron pyrites ) . There are cheaper imitation, including , for example , ordinary copper with gold plating. To avoid unnecessary spending on advanced tests , worth a try first the following preliminary tests :

-scrabble product on bisque , and look at the left strip. If it is dark in color , most likely that the pyrite. If golden yellow – is not gold
-Further , conduct product by ordinary glass. Since gold is softer glass , it should not leave a trace
-try to check iodine. To do this, apply a drop of iodine on gold product for 3-5 minutes , then wipe off with a napkin. If the stain metal remained unchanged , then gold is likely authentic
-Bring the product to a magnet. If it is attracted to a magnet , it is probably not pure gold
-if you do not have a magnet, or the result is in doubt , use the gold to check the authenticity of the vinegar. Lower the product for some time in the vinegar if it will darken – it is a fake .

None of these methods will not detect 100% accurate if the sample is pure gold or gold is not there at all , but you will get at least approximate results.
Checking the authenticity of gold acid / scratching

Checking acid – scarring – this is the least expensive alternative as compared with other tests to determine the purity of the gold , however, it can provide a fairly accurate results. Can be checked at home. You need to buy a set for testing acid in professional chemistry lab or shop for jewelers . The test is performed in series, with gold needles with increasing gold content ( samples ) . Acid gold to the authentication can be used almost any – sulfuric acid, nitric acid and so on.

The products apply micro scratch , scratch and drip on some acid . Then compare what color will remain in the scratch ( comparing it with needles ) , and draw a conclusion about the probable metal sample .

You can also use the so-called ” touchstone “, which has a matte polished surface. Slightly ” scrabble ” checked your product on touchstone . To do this, first select the least conspicuous portion decorations press and rub the gold fragment of stone several times. Do the same with the sample from the test set . You can choose 2-3 validation sample , which you think are most similar to the gold content to the scanned product. ” Let me know ” each of them on the stone as close to the track from scratch , left testable product . Then, map the trail left by a tone touches all known reference sample (ie , with traces of samples for testing) .

Test samples and definition of gold by means of special devices

More advanced methods for determining the purity of gold in the article involve the use of devices that give more accurate results. The most common are electronic testers that exist in many different forms – both for individuals and for professional laboratories. Electronic testers use a liquid droplet to scan a sample and generate digital signage purity .

A more expensive technique is to X-rays , used only in vitro. With it , an analysis of the dispersion wavelengths , defining not only the sample (content) of gold, but the full composition of a gold alloy .


Assay typically used to determine the purity of gold larger samples . It is rarely used for testing coins or jewelry because of its ” destructive ” nature . The fact that a fragment of the sample has to melt and separate from the sample. Separated portion of the sample is then heated to extremely high temperatures , and fused with lead and silver, which play the role of agents , separating and collecting pure gold at the end of the process. The resulting product was weighed to determine the initial purity of the sample.

    know-how here with mates.

  4. Often you can hear from their friends, or face the very situation when gold initially bright and shiny suddenly begins to darken and thicken. That is to change its original color. And if you try to clean it, then on the product remain some white streaks and scratches. Because of what the heck is going on? It is hardly present and expensive gold product here so suddenly change its tsvet.V result there is a need to check your gold product for authenticity. Alas, in the home, such an experiment is practically impossible to produce. Methods exist, but they do not always show the real result. For starters, you can check the density of the product. But even if the product of real gold and fake is not, then it can be any of the cavity, even if it is tiny. But really the same weight and fineness specified on the product label are real and match the items themselves.
