Our jewelry is marked with different hallmarks:
Internationally, Ag 925 stands for sterling silver, whereby the abbreviation Ag comes from Argentum, the Latin name for silver, and the number 925 indicates the purity in per mille. Sterling silver consists of 92.5 percent silver and 7.5 percent other metals, usually copper. Alloying with copper is done to optimize the mechanical properties of silver when used as a jewelry metal, in particular to increase its hardness. There are also silver alloys with lower purity, but we only use high-quality sterling silver.
Au 750 is the name for 18 carat gold, regardless of its color. The abbreviation Au stands for Aurum, the Latin name for gold, and the number 750 indicates the purity in per mille. Au 750 consists of 75 percent gold and 25 percent silver and copper. Whether the gold has a rich yellow tone or tends to be more reddish, which is then referred to as rose gold or red gold, depends on the proportion of copper added. The lower the silver and the higher the copper content, the more the gold color shifts towards red. In white gold, however, palladium is added as the color-determining metal instead of copper.
Another hallmark consists of the letter abbreviation MiG , which is framed by a pentagonal cartouche. The letters stand for Made in Germany and the five corners of the frame symbolize the five fingers of the hand and refer to the high proportion of manual work.
