Silver - Silver is a chemical element that is marked with the symbol Ag (lat. Argentum) in the periodic table. The precious metal has the atomic number 47 and is counted in the series of transition metals. It is easily deformable, but can still be given a very firm and durable shape, making it one of the most commonly used materials in jewellery making. This is due not only to the properties that make it a flexible material, but also to its attractive bright appearance, which makes beautiful jewellery possible. Silver has the highest conductivity of all known elements and among metals also the highest value of thermal conductivity. Silver is extracted from silver ores, lead ores and copper ores. The shiny white precious metal is rarely used as pure silver for jewellery, the numerous alloys are more frequently used here. The most important alloys are copper-silver alloys, which make silver harder but not brittle. The fineness of the silver present in the alloy is decisive for the classification of the material. 800, 835, 925 or 935 silver are the known alloys, whereby the number indicates the fineness in thousands of parts of silver. This means that the best known silver, 925 silver, also known as sterling silver, contains 92.5% pure silver.
