You have doubts that the gold items you have purchased or stored in your home are genuine.
Don't rush to the jeweler, try to determine their authenticity yourself. How to do it? This is what we will talk about in this article.
You can test gold for authenticity at home using quite affordable means. It is not as difficult as you think.
Besides, extra knowledge in such a matter will not hurt. You will need: a used old toothbrush, toothpaste, a cotton swab and a container with water.
However, the main element in all your further actions will be iodine. Yes, the same iodine that is in every medicine cabinet, in every family. If for some reason it is not there, then it can be purchased at any drugstore.
When everything is ready, take a cotton swab and dip it in iodine. After that, apply a small amount of the substance to the gold jewelry you want to check.
We carefully observe the reaction. The higher the gold standard, the less various impurities and the lighter the applied drop of iodine will be.
If the substance turns dark green, then the product has a low fineness, about 50%.
Water, a bath, a toothbrush and toothpaste are required to remove iodine from jewelry.
Another method to independently determine the authenticity of gold is to use its physical properties.
We know from school that gold not only does not enter into chemical reactions well, but it also does not become magnetized.
Take a magnet and bring it to the product; if it is attracted, it certainly contains a large amount of other impurities.
If you use the above methods to determine the authenticity of gold items, you will know what kind of jewelry you have purchased and what value they have. But for a full guarantee, you should still contact a jeweler.
