There are several degrees of purity of silver, depending on the actual percentage of silver contained in the jewel. We must bear in mind that pure silver is too soft, so it is necessary to combine it with another metal to be resistant. In jewelry we use silver alloys with copper, precisely to guarantee the strength and hardness of the jewels. The percentages of both metals are expressed in decimals of at least three digits and hence the real silver must bear the 925mm stamp; which explains that the piece is composed of 92.5% silver and 7.5% copper. In Spain there are two types of official Sterling Silver

o   Silver of First Law (or silver 925 mm): the silver content must be equal to or greater than 92.5%.

o   Second Law Silver (or 800 silver): the silver content must be equal to or greater than 80%

The minimum thickness that the silver layer must have to be considered as a quality bathroom is 0.02 millimeters; otherwise, the applied silver layer will disappear in a short time.

Rhodium is a metal of the platinum family; of a high economic value due to its scarcity. It is still used in gold and silver jewelry to prevent rusting and to create a protective film that makes jewelry take longer to scratch. It also allows you to give the jewel a white, black or pink finish.
