Alloys
Noble metal
The color and quality of the precious metal are determined by the type of precious metal and the precious metal content. Pure gold is referred to as fine gold. In its pure form it is free of other metals such as silver and copper. Fine gold has a light yellow color, which does not change in the air, since fine gold does not combine with the oxygen in the air. These special properties classify gold as a precious metal.
A shimmer for eternity
In its pure form, gold is the most ductile and softest metal. For this reason, it is mixed (alloyed) with other metals before processing. These alloys are of decisive advantage in jewelry and especially in wedding ring production, because they often have different, more durable physical properties than metals in their pure form. Wedding rings can often be made harder and more resistant, and each alloy gives the ring its unique shimmer of color. Adding silver or palladium makes the original shimmering yellow color of gold lighter, adding copper makes it darker or reddish.
Degrees of purity
The degree of purity of gold can be expressed in different ways. A common measure in the 19th century was – and is partly to this day, especially in the United Kingdom and the USA – the “carat”.
The number of carats (kt) relates to how many parts of 24 total parts of an alloy are pure gold (e.g. 24kt gold means that 24 of 24 parts are gold, i.e. 24kt denotes 100% pure gold). The 8kt, 14kt, 18kt and 21kt containers we use contain 33.3% 58.5%, 75% or 90% gold, respectively. In Europe today, the indication that the proportion is based on 1000 parts by weight is more popular. This means that in alloy 585 a total of 585 out of 1000 parts by weight consist of fine gold.
With a hallmark (embossing) in each of our rings, we guarantee the actual fineness of each ring.
