Doubts as the acquired products, an unexpected find, an inheritance in the form of ancient coins - the desire to check the metal for silver can be due to a lot of various reasons. Next, we will talk about whether it is possible to check the silver at home for authenticity, determine its sample, various methods of verification and J, where to apply for an expert evaluation.

Check whether silver is present by the presence of a stigma

Silver products sold in the international market should have a marking in the form of a stigma indicating a metal sample denoting the percentage of silver and impurities. So, on sterling silver there is 925 sample. This means that the alloy of 92.5 percent consists of pure silver and 7.5 percent of copper. Silver 900 and 800 samples are called “monetary”, in such alloys the content of impurities reaches 10 and 20 percent, respectively.

It will be required:

• product for verification;
• magnifier;
• the tool and accessories for cleaning silver (in cases where the product is significantly contaminated).

Procedure:

1. If necessary, clean the product from pollution.
2. Find the stigma. It should be located symmetrically in relation to the edges of the product. The numbers should be clear.
3. The lack of stigma cannot be one hundred percent evidence that the product is not silver. Perhaps it was not certified or was produced in countries in which the application is not a mandatory point.
