925 silver test - science and investment

Silver is a soft metal, from which it is enough to create products of any complexity and different sizes. It is often mixed with copper to make it stronger. For a long time, a mixture of these metals was used to make coins. The test at that time was the 500th (50 percent silver, 50 copper). However, more valuable coins were created , for example, silver was used, sample 925, which was valued more. Often such an alloy was taken to create exceptional commemorative coins and jewelry.

Nowadays, 925 silver sample has in its alloy 7.5 percent copper. Such metal is suitable for creating many jewelry - rings, necklaces, bracelets, brooches and much more. Also these products are quite popular, because they are inexpensive and affordable for many people. Putting them on the beach in the summer is not recommended, because they are often lost, which can not but please people with metal detectors. However, not everyone knows what to do with such findings. And after all 925 the test of silver costs three times more expensively, than usual. Often, when making jewelry, precious and semi-precious stones are inserted in them, for example, chrysolite. Such products look very impressive, they will never go out of fashion. This, of course, applies not only to the specified metal, but also to gold. Fantasy jewelers have where to play out, because silver (925 test) is very plastic. Many women and men prefer it to other precious metals.

Science and silver

However, this alloy is used not only to create beautiful gizmos, it also found application in science. Especially demanded is 925 silver sample because of good electrical conductivity. In addition, this metal is used in photography, when creating mirrors, where silver is preferable to aluminum for better reflection. Sometimes this metal is used to disinfect water.

Allergic reaction

Some people are allergic to silver. Therefore, use of such dishes is not recommended. Dressing products from this metal to small children is also not worth it.

Samples of silver. How are they calculated?

At present, there is a metric system in Russia that calculates the percentage of silver per 1000 units of that alloy in which it is a part. This means that 925 silver sample in one kilogram contains 925 grams of silver, and the rest is copper. Before the beginning of the twentieth century, there was a slide valve system. Often it was possible to notice on the coins the words "spool 2 shares 10.5". The whole system was built on a unit equal to 96 goldsmiths - pound. In addition to 925 tests, there are other, lower. For example, 800, 830, 875, which are mainly used to create silverware and dishes. Investments

Many people invest their money in silver coins, because the cost of investment coins every year is higher and higher. However, everything depends on the world price, which determines the value of precious metals. On each product of such an alloy, a sample must be finely written. Most often without a magnifying glass it can not be seen, but it is available, because that's how you can distinguish a precious metal from a fake.
