Silver has been known to mankind since ancient times. This is due to the fact that in the past silver, like gold, often found in its original form - it did not need to be smelted from ores. It has predetermined a rather significant role of silver in the cultural traditions of various peoples.
Silver is a metal of brilliant white color with very high (95%) reflectivity, viscous, ductile, plastic; it is well polished, cut, twisted, rolled into sheets with thickness up to 0.00025 mm and stretched into the thinnest wire. Silver is stable in air and in moist environments, does not react with fusible and hydrochloric acids, and dissolves in concentrates of nitric and sulfuric acids.
In its pure form, silver is used to silverplate objects made of non-precious metals and as a component of gold and silver solder; as a material for jewelry making, it is used only in the form of alloys (more often with copper).
In many countries, silver is used in large quantities as a material for table and interior decoration. Silver is also widely used in the manufacture of jewelry: Earrings, Ring, Brooch, Pendant, Bracelet, Necklace, necklace, cufflinks, etc. And silver can be used in combination with gold, enamel, niello, precious and semi-precious stones, pearls, coral, ivory.
The main characteristic of silver is that it darkens over time (as the saying goes: black). Silver jewelry can turn black a month after you buy it, or maybe even a few years later. Why?
The jewelry we buy contains copper, which is the strongest oxidizing agent. The main oxidizing agent is sweat. In addition to salts, it contains amino acids, which include sulfur. Under the influence of sulfur-containing compounds, silver turns black. If you sweat a lot, all your jewelry will turn darker. This may simply be due to prolonged physical activity.
The causes of silver blackening can be very diverse. The sample of the product, the chemical composition of the air, and the humidity of the environment all play a role. You may have moved to an area that has more hydrogen sulfide in the air or soil.
What is a rhodium plated silver? It is a silver jewelry that is coated with a thin layer of another precious metal from the platinum group - rhodium, which makes your jewelry shinier, more beautiful and protects it.
Rhodium is more expensive than gold, which raises a natural question: why is rhodium only used for plating, rather than as a base metal for jewelry making? The answer to this question is another characteristic of this element - it is extremely fragile.
Recently, silver jewelry has become incredibly popular due to its affordable price, and more and more people prefer silver over gold. And it is precisely because of the availability of silver jewelry that it is much easier for you to express yourself with their help, buying different versions of silver rings, silver earrings, pendants without affecting your budget.
Rhodium plating gives silver jewelry a brighter, shinier look, makes the product "play" and look richer. People often mistake a piece of rhodium-plated silver jewelry for white gold. It's no wonder: rhodium is a precious metal from the platinum group, one of the rarest chemical elements on earth. Rhodium is a very hard, strong, scratch-resistant metal. It also does not fade, which is very convenient. These are the qualities that make it so attractive for silverware.
Rhodium-plated silver combined with stones: Amethyst, Topaz, Turquoise, ruby, Garnet and others give the jewelry an incredibly elegant, sparkling appearance. And silver jewelry with cubic zirconia looks just as good as diamond jewelry, although it is many times cheaper.
The care of rhodium-plated silver jewellery
- Although the rhodium layer is very resistant to wear, it still requires care. Try to remove your jewellery as much as possible at night and during sports activities or when visiting the sauna. Rhodium can begin to "climb" if it is in prolonged contact with the skin, or more specifically, glands containing grease and sweat.
- Wear jewelry after applying alcohol-based lotions and perfumes to the skin, not before. Make sure the liquid soaks into the skin and then wear the piece.
- Avoid contact with household chemicals. For example, when washing dishes.
- If possible, remove jewelry when going to the pool or bathing.
- Never use ammonia-based products to clean rhodium products. Toothpaste with tooth powder is also not suitable. At most, rinse in warm water, wipe dry with a soft cloth and polish with a special jewelry cleaning cloth.
