At Juwelier Wagner, we have over 100 years of experience in the traditional goldsmith’s craft. This knowledge and the outstanding craftsmanship of our goldsmiths ensures perfect processing of our jewellery.
Before a jewel can achieve its peerless radiance, a number of essential processing stages have to be carried out. Only then will the end result produce the desired effect. To ensure the highest possible surface quality, platinum or gold is processed using appropriate forms of process and machine technology, such as polishing with a polishing compound. This polishing also serves as a basis for the final polishing process which then takes place. This is done in several stages until a brilliant result is achieved. A number of different abrasive materials are used. Because of its special characteristics, the process of polishing platinum is a challenging task.
In our workshops, the polishing process can remove scratches from stainless steel, gold and platinum watch cases, as well as bracelets made of these materials. Jewellery items made of gold or platinum also regain their radiant shine after careful polishing. The friendly and professional Wagner Team are a reliable source of knowledge in these matters.
An element of design
As an element of design in a piece of jewellery, individual parts of the surface can also be matted. The transition between shiny polished surfaces and matted parts can be highly effective. Precious metal is matted chemically by pickling, or manually with abrasive paper and pumice, or mechanically using a sand blaster and special granulate.
Jewellery can also be satinised. Lines are drawn crosswise by hand or machine using a lining graver to create a finely matted silky surface.
Schmuckstücke können auch satiniert werden. Mit einem Fadenstichel werden dabei per Hand oder maschinell kreuzweise Linien gezogen, wodurch eine fein mattierte seidenartige Oberfläche entsteht.
Filing is another basic technique that is routinely mastered by goldsmiths. Filing is carried out not only to trim the jewellery item during the manufacturing process, but also as an element of surface design, giving the piece a special character. With a well-honed filing technique, a goldsmith can precisely execute each stroke of the file on the piece of jewellery. Round files, triangular files, half round files and square files are used in addition to flat files. In the processing of metal components during jewellery manufacture, residual imperfections or burrs frequently arise which have to be removed.
Another surface treatment technique is electroplating, whereby (for example) a piece of jewellery is given a metal coating by means of electrolysis. This process makes the surface more resistant and less susceptible to scratching.
Specifically in the case of white gold, the related process of rhodium plating produces an evenly beautiful colour on this precious metal.
