What do you think of this ring?

[Arkteia]

I bought it in the country occupied by Nazi Germany during WWII, or being the Axis member (depending on whom you talk to). The owner said it was German from 1930es and even told me the name of the master. Why I bought it, GOK, but it looked at me.
Now I saw a ring not unlike this in idea here

(I like the items this vendor sells and I think they are interesting, I follow him, only never pulled the trigger.)

I know my ring is not Faberge for sure. But a German jeweler of 1930es it could be. Can anyone comment on this style? How typical it was, should I invest into assessment, how does the tourmaline look, what can one say about the jade/jadeite? Photo is under very low light, so the stone does not look its best.

ETA the assay mark is 750

the stamp next to it I can not see in the loupe. Need a huge microscope. It looks slightly like Dublin one, meaning, big, but I can not see it well. Then it says 0.45 ct. then W-P1.

I think W PI means VV to pique 1 (included 1) for diamonds. So, likely it came from the country that uses pique classification (could be Germany). Need to sort out the stamp

The Fabrege piece does not look Fabrege to me, and more of a modern post ww2 piece. Fabrege is still in business, and some modern pieces are assumed to be older. I could be wrong though.

@TL, I did not want to get into Faberge because even real Fabergé provenance is incredibly complicated ))) . There are such fights in Russian-speaking press about the provenance, lol! They had several shops and workshops, too.

I did not think that my ring was from Fabergé. I though it could be from WWII. But you are right as Googling indicates that all German war stamps, including on gold, are the same (((. There is a tiny question as to for how long after 1933 famed German goldsmiths were allowed to use own stamps (they were variable), but I think that you are right and the item is postwar.

(Studying gold stamps is an cool deal in itself. My ring was bought in Latvia, but the stamp is not Latvian Soviet, that one I’d recognize, too).

I guess I have to set up a macro iphone attachment and take a photo, and search. Thank you.
