Silver is a precious metal prized for its white luster that can be polished. It is a malleable transition metal and is chemically not very active. It does not change in water or air and its surface is clouded with hydrogen sulfide, ozone, and sulfur-containing air. Because of its appearance, it was first named with the Latin word argentum , which means white or shiny. The word silver derived from the Latin word platus , which means flat or flat. When polished, silver is capable of reflecting 95% of light; which is why it is used to make mirrors. The density of silver is 10.5 times greater than that of water. As for jewelry, silver is one of the noblest metals to work with and the most beautiful in appearance. It was believed to be a gift from the moon to humanity. The oldest pieces created with silver are examples of the jewelry mastery of different cultures. It is difficult to find silver in its pure state because, in most cases, it is associated with other metals.
It is found in lead, copper, zinc and gold mines. The largest exporters of silver are Mexico, Peru and China. What is 925 silver? The purity of precious metals is measured with a system in thousandths, known as “law”. Indicates the proportion between a precious metal and its alloy. A metal evaluated at 1000 thousandths is 100% pure. With silver, grades 950, 925, 900 and 800 are used. This law arose when America and its rich mines were discovered. The discovery caused the prices of gold and silver to change abruptly. That is why a series of classifications for different USA Phone Number metals and precious stones began to take shape. Although purity is very valuable, if a silver accessory is completely pure it is impossible for it to maintain its shape because it is a very malleable metal. It would surely be deformed. It is because of this that jewelers and goldsmiths must mix pure silver with other metals such as copper. For a piece of jewelry to be labeled as silver it needs a minimum percentage of 50 percent.
That is, at least half of the metal must be pure silver. In most cases, silver accessories or jewelry are worked with a purity of 92.5 percent. The remaining 7.5 percent corresponds to another metal. This is why many pieces of silver are marked with the numbers 925, to provide information to those who admire or buy the jewel. To make this mark, a punch is used that has numbers on the tip. If the piece is very small and risks being deformed, it is not marked. The purity law and the 925 mark are a guarantee of quality. Therefore, it is important to make sure you get this purity information about silver before purchasing it.
