Roma distinguish gold from this very simple, because it does not have the stigma and soluble in all acids (Real high-quality gold can be dissolved only in selenium acid and only at a temperature above 200 C). Jewelers do not consider the Roma gold precious metal.
Composition
Beryllium copper (gypsy gold) is produced from copper and beryllium, the composition is resistant to corrosion and high strength. Since beryllium is very expensive to replace it Roma learned to cheaper analogs as mixtures of chromium, steel, nickel and copper.

How to check a fake?
Many people have seen on the Gypsy wedding rain of gold, but few people thought about the fact that not all that glitters is gold. Therefore, if the planned purchase of a piece of jewelry, you must know how to distinguish real from fake precious metal. When choosing a gold jewelry should pay attention to the following:
- a well readable stamp, which contains the metal sample;
- all the small details and the stones have attachment points must be securely fixed;
- fasteners on jewelry must be easily opened and closed;
- the corresponding price.
If the jewel meets all the above points, but still continues to cause a lack of confidence, you can check it out "to the tooth". The present gold is a soft metal and is easily tooth pressing. Besides, There are other ways to check the authenticity of metal at home.
- The sound. We need to take the gold product and throw it on a hard, smooth surface (eg table). If it is true, it will emit a pure crystal bell. This method can not check the length of gold jewelry (bracelets, chains).
- Strength. If the decoration scratched with a sharp object, and under the bottom layer of Dark Glory is found, then it is a fake.
- Also check out the gold can be vinegar - real metal does not change color, and fake immediately darkens. If the drop to the surface of the product iodine and three minutes later, nothing happens, it means that you purchased a quality precious metal. At the same bogus remain black or white spots. Many also checked jewelry magnet, real gold does not react to it.

The prints must be exactly the same. In addition to all of the above, jewelers are advised to check the authenticity of the gold, closely examined the product in the daylight and in the shade.
Precious metal retains its color and shine, regardless of the level of illumination, as for the fake, in the shadows, she looks pale, dull, and the sun shimmers and glitters.
Special attention should check the authenticity of jewelry using the method of Archimedes. The only thing that it is suitable only for large weight jewelry. They should be dipped in water and measure how much fluid will be displaced. Then, using the formula in physics, it is necessary to calculate the weight, and to find out whether it is genuine.
