Silver has been known to mankind for a very long time. It is connected with the fact that in earlier times silver, just like gold, often occurred in its natural form. This means that it was not necessary to extract it from the ore, and this is what gave silver a significant role in the cultural traditions of many peoples.
Silver is a white shiny metal, which has a very good reflectivity (95%). The metal is viscous, malleable and easy to shape. It is easy to polish, cut and bind together. In addition, silver rolls very well into sheets 0.00025 mm thick and can be expanded into an ultra-thin wire.
It is very resistant to air and high humidity, does not react with aqua regia, hydrofluoric or hydrochloric acid. Dissolves in highly concentrated nitric and sulfuric acids.
Silver is used in its pure form for silvering base metals. It is also used as one of the components in gold and silver soldering. For the production of jewellery, silver is used only as an alloy (usually with copper).
In many countries this noble metal is used for making large quantities of objects for serving the table and for interior decoration. It is also widely used in jewellery making.
For example: earrings, rings, brooches, pendants, bracelets, necklaces, chains, cufflinks etc.
Silver can be used with gold, enamel, precious and semi-precious stones, pearls, coral and ivory.
The peculiarity of this metal is that it darkens with time (turns black). Jewellery made of silver can turn black after only a few months, but also after a few years. Why is this?
The jewelry we buy contains copper and that is what oxidizes so much. The oxidizing agent is sweat. It contains salts and amino acids that contain the sulfur. When exposed to sulfur-containing compounds, the silver turns black.
With very heavy sweating, all decorations will darken. This can be the case with prolonged increased physical stress. If the jewelry darkens only in a certain place on the body, it would be advisable to check his hormonal system.
There can be many reasons for the darkening of silver. The silver sample plays an important role. Also important are the chemical content of the air and the humidity of its environment. It may well be that you have moved to a site that has too much hydrogen sulphide in the air or in the ground.
Another cause can be the use of new cream, makeup or ingestion of any medicine.
So, in case your silver jewelry turns black, then it would be advisable to listen to its wellbeing. In the event of the occurrence of painful symptoms, contact your doctor. However, in case everything is fine, there is also no need to worry.
Silver is the whitest of the noble metals and this property is very actively used in jewelry making. The neutral color of this metal combines very well with black, natural color for him - because when oxidized, silver darkens. And the combination of white and black silver is very impressive.
At the same time, the combination of engraving and blackening allows to use expressive means and the process of another art form, namely, graphics.
The combination of silver with other light colours is also interesting. The metal serves as a good frame for brightly coloured gemstones, semi-precious stones, jewellery and artificially synthesized stones and for jewellery enamels.
