Featured Amber ring questions

I picked this up for $20. Google lens is pointing to vintage Soviet Baltic amber, but they are not always correct. What do you see? Age, country of origin, silver purity, etc.?

 

Beautiful ring, and yes to amber.
The marks are blurry, but the one on the left looks like a Polish mark, the girl with headscarf with a 3 for .800 silver, 1963-86. The town mark looks like a K, for Krakow.
So is indeed Baltic amber, but the mark looks Polish to me, not Soviet.

Polish silversmiths love the Art Nouveau style, which has become a Polish traditional.

 

Thank you! I have not seen a ring like this searching the internet.

 

I have never seen one like this either. If I had, I would have bought it.
