Machine gunner ring, opinions please!

[vellocino]

Hi, I just bought a set of 3 rings, one of them depicts a german machine gun, the other one a militar design or not, that I don't recognize and a gold fur eisen ring that shows a monogram that I can't decipher.
The machine gunner ring shows the words welt krieg on both sides and its marked 800 for silver content. Its around a size 7 on my opinion, but the slim and delicate band tells me that probably its a sweet heart piece for a lady since it not as big and sturdy for a man. I would really want to hear your opinions on this one, it is a period piece or not?.
About the green enameled star and circle ring, does anyone recognize the design? Can anyone help me decipher the monogram on top of the gold for iron one.
I really like the machine gunner ring, I instantly thought about showing it to the machine gunner badge collectors. Hope you like them.
Thank you

Second, the green star and circle ring marked 800 and the monogram on the gold gab ich fur eisen ring.
Thanks again for your opinion.

I don't see any red flags. Does a magnet stick to the monogram ring? (It should.)

Thanks for the response. Surprisingly this one is non magnetic, a difference of the ones received when exchanging gold or other important war related metal. I collect gold for iron items, but I took a chance with this one since I thought look singular.
I will research it a little more before discarding it as a non-period gold for iron ring. Any idea on the monogram, does the style of the letters looks like 1910's in period? Thank you

Here it is the inscription

I believe that the green "ivy" ring is for the American 4th Division, which were briefly part of the army of occupation following WWI.

The MG ring looks ok to me.

Thank you

Thank you, Don Doering for you knowledgeable opinion, Dave G I think you nailed it with the ring bearing the insignia of the U.S. 4th Infantry Division. The Ivy Division occupied the region of the Rheinland-Phalz at the end of the armisticie until July 1919.
Since the ring has a 800 silver mark, it is correct to think the ring was made in this occupied part of Germany?
Silver items made in Germany after 1888 are marked .800 (this is 80% silver content), and this is the standard for silver pieces made in Germany from that time on. (Quoted on http://www.beerstein.net/articles/bsj-2c.htm). 800 stamp was not used on jewelry made in USA, France or elsewhere, just Austria and Germany made use of the 800 stamp. Please correct me if I am wrong.
Getting back to the machine gun ring, I was lucky to get it since on all my few years of collecting I haven't seen another one like it. If someone else has another example please share it for comparison.
Thank you all for your opinions.

I have seen other MG rings in the past, and they looked exactly like yours. I don't own one, or have any photos to share- sorry.
