The colour and mixture of the precious metal is called the alloy. Since none of the precious metals used (gold, palladium, platinum) is suitable for further processing in its raw state, they must be mixed into an optimum alloy by adding further metals. This is also what gives them their colour. While fine gold has a yellow hue on its own, adding silver, chrome or platinum metals can remove the colour and the result is what’s known as white gold, not to be confused with silver. In this way, alloys are created by melting two or more metals together, which does not serve the purpose of stretching, but for better further processing and to vary the colour. This diversity allows you to choose exactly the alloy that best suits your personal taste or requirements.
A 333/gold alloy contains 33.3% fine gold. Since this alloy consists of a large proportion of by-metals such as silver, it is particularly porous, susceptible to scratches and the colour can also fade. We therefore recommend an alloy that is at least half gold, such as our 585 gold alloys.
Different shades of gold are achieved depending on the composition of the alloy. To ensure that our high-quality white gold alloys with a high gold content still have the pure white colour and the golden yellow does not show through, they are coated with an additional layer of rhodium. This coating may wear away somewhat through everyday contact, but it can be redipped at any time.
