It is quite possible to make sure at home in the authenticity of a gold product, but the reliability of the result is only 80-90 percent. The simple checks below can pretty much keep you safe from wearing a trinket.
Perhaps everyone knows that precious metals do not magnetize at all, therefore, if your product does not react at all to a magnet, then most likely it is gold.
However, in this case, it is worth remembering that aluminum, copper ornaments covered with gold do not react to the magnet either. Here, first of all, you need to pay attention to the fact that such products are much lighter than gold ones, because gold is a very dense and rather heavy material.
Absolutely any metal, if held over an unbaked ceramic tile, leaves traces, gold is no exception. To check the authenticity of a gold jewelry, you need to bring them along the surface of the tile, then look at the trail. If the product is gold, then the line will be gold, if not - black, gray or brown.
Another option to test gold for authenticity is to use silver nitrate. You can buy it at any pharmacy, in medicine it is used to cauterize wounds and is called a lapis pencil.
So, it is necessary to slightly moisten the metal with water, then make a dash on the product. If the features are not visible, then the product is gold.
Gold is a noble metal that is highly resistant to chemical attack. This feature of this precious metal allows you to check its authenticity by applying ordinary iodine or vinegar to it. These substances do not leave traces on gold, for that spots of different shades appear on other metals (this depends on the specific metal).
