Need help with marks on a bracelet - spain

[whiteparakeet]

Hello,

I'm new here and need help with this marks. They are on a old, handmade bracelet. I think it's silver, maybe 800 or less, because it has little spots of "Green" on it. I live in Spain and I bought the bracelet in Spain in a Charity Shop - where the people don't know about the origin, and don't know about the marks. I found them at home with a lens, they are very small. Can anybody help me or give me a approx. estimate how old it can be? Thank you very much and kind regards, Adele
