Jewelry process

There are various methods with which pieces of jewelery can be processed, for example to make them particularly shiny, matt or colored. The production of artificial stones, for example, also falls under the major topic of jewelry processes. The most important of these are briefly presented below:

Rhodium plating and platinum plating

Both processes involve electroplating, in which the piece of jewelery is given a wafer-thin metal coating through electrolysis. The process is used for silver jewelery to achieve a stronger shine and to prevent the typical dark tarnishing in the long term.
Rhodium and platinum both belong to the so-called platinum group and are also characterized by good hardness and consequently good durability, so that the pieces of jewelry are also less prone to scratching. This is why white gold in particular is also popularly rhodium-plated, especially since the rhodium-plating brightens it up a little - while the even more durable platinum-plating can have a slightly grayish tone. The black rhodium is an exception, so it is possible to color the (silver) jewelry anthracite-black.
Both processes refine the silver jewelry, are hypoallergenic and of course not toxic to the jewelry wearer.

Oxidize ("vintage silver")

The typical black tarnishing of non-galvanized silver jewelry is due to the oxidation process, in which oxygen usually plays a major role. In the case of silver jewellery, in particular, this effect is deliberately desired in places and is brought about artificially. Due to the somewhat antique look of the oxidation, one often speaks of "vintage silver". Such pieces of jewelry should not necessarily be subjected to a silver immersion bath, because then this oxidation is temporarily lost.

dull

Every now and then, jewelry is deliberately not polished to a high gloss, but instead matted. Various chemical and mechanical processes are possible for this. Sandblasting is often used, which creates an evenly matted impression - when using mechanical aids (e.g. polishing or brushing), on the other hand, a matting is created in which the applied direction remains more or less clearly visible in a fine pattern. Be it lengthways, crossways or diagonally.
Depending on the application, somewhat coarser or finer impressions are created. The so-called ice matting is now very popular for wedding rings that are worn all the time. For this purpose, the surface is scratched "criss-cross" by an experienced finesmith with diamond files and sandpaper, so that later signs of wear remain unobtrusive.

Enamel

Enamelling is used to provide silver jewelry with colored surfaces. A heated and thereby melted glassy mass is fixed on the carrier material. In addition to the artistic effect desired in jewelry, enamel always has a protective function for the metal underneath.
There is enamel in all colors, be it glassy, ​​full-colored or with glitter effects. It is applied by hand and it can be used to create wonderful color gradients and lively images on the pieces of jewellery.

Zirconia production

The process for making these artificial diamonds was developed in the former USSR in the 70s. The zirconium oxide powder is heated and melted. At the end of the process, a block is created, inside of which the crystals have grown. By adding certain elements, not only clear crystals, but stones in a wide variety of colors can be produced. It is also possible to create artificial inclusions.
The zirconia differ from diamonds by a slightly different light refraction and density, whereby a high-quality zirconia crystal can actually only be distinguished from a real diamond by measuring the thermal conductivity.

Nano Gems

Artificially produced gemstones are called “nano crystals”. What matters here is less the synthesis process than the impression that the finished stones can give: Nano gemstones can hardly be distinguished from real stones with the naked eye.
Thanks to their artificial synthesis, they are characterized by reliable homogeneity without inclusions. All colors are possible, including special optical properties such as translucency or opalescence - an almost magical shimmer that makes the stones shine in different colors depending on the incidence of light. The Nano-Gems always have good hardness and can also be cut or faceted like real gemstones.
In summary, it can be said that the artificial nano-gemstones have nothing in common with the corresponding real gemstones in terms of their chemical composition - but they can hardly be distinguished from them with the naked eye and are just as durable.
