Typically, silver for jewelry use is alloyed with copper. Nickel is used for applications needing a harder alloy. But silver can be alloyed with nickel, tin, zinc, cadmium, lead or several other nonferrous metals. Any silver alloy can turn you green or black due to the reaction of the alloy metal to your skin in the presence of moisture. Usually green is a reaction to copper or nickel while black is reacting to tin, zinc, or lead. The higher the silver content number, the less likely to see a discoloration.

Just an added note - some individuals tend to sweat more and/or have a more acidic sweat. This will cause any discoloration to occur faster and more frequently.

Just for the info....... here an old fleamarket , German ring with moon-crown stamp .

Testing tools for silver and gold from the Utecht Essay Office, that existed from the19th century till 1986. On some is stamped the amount content of silver, zinc and copper, if I’m correct.

Some tools have silver or gold testing ends .

You can see which have a high copper content ... the surface turned unwanted in a green corrosion.

well the green can be good! It's telling you what is in the alloy! WHY is it when you wear a ring marked 835 all day and night into the next few your finger will be fine,,,and why with other with same mark 835 will turn your finger blackish or greenish after a days wear?!?


I don't know enough to say for sure but - IF something is stamped 800 on it what is the other metals its 'alloyed' with to make up the rest of the base content.. Can any metal be added in??..

And please,,anyone that knows again please jump in and correct and or inform us to understand... I know Hapur known,,and 'Ed' the watchmaker,, Vern too, but they're busy...

- So, I take it that the tests are to see what the other metals are.. Silver you can add copper to that I know,,,,but can you add lets say zinc? Iron? does it have to stay with nonferrous? [not magnetic] .. - * Benten thanks for posting this. Its important and we should know a little at least about it..
It says 19th century but wouldn't doubt if it was known/testing, etc. in the 1700s!
