  1. What are these marks?
  2. In what country produced the brooch?
  3. In which year produced the brooch?
  4. Which firm or master produced this brooch?
    Thanks in advance!!

Help me please !!! :question: :question: :question:

The “833” is probably the purity of the silver, or 83.3% pure. The Dutch used a lot of 833 silver. Can’t help beyond that.

Uncle Vic

Thank you uncle vic!!! :smiley:
And who can tell about the stigma and the approximate location of production jewelry??
How about her age??
Thank you!

Help me please !!! :frowning:

The ZII mark to the right is a Dutch import mark for .835 fineness, introduced in 1953.
I’m thinking Germany for the makers mark.

Thank you!
But the sample is 833 and not 835! Maybe there are assumptions??? :confused:
