Hey everyone!

I got some rings from my grandpa when he passed away and no NOTHING about them and can't seem to find anything relevant. Any input would be much appreciated. Sorry if this is in the wrong area.
(The skull and bones one is hard to see but I think says Mexico 935)

Let me bump this for you
Im pretty sure 935 mean 93.5% silver
Do Grandpa's rings fit you or will they need to be sized ?
Its really lovelly you inherited these rings of his

I don't wear jewelry lol. Just my gauges in my ears. Im really more interested in their story or history. They are super pretty

Nice rings! The blue stone looks like a topaz, but it is impossible to determine what a stone is by a picture. I can’t make out the silver and blue ring, is it an initial or a design? Sadly it is difficult to learn history on pieces as different countries have different rules on metal purity stamps, there isn’t a great database of jeweler’s stamps, and jewelers change stamps over time. \

My grandpa's parents came from Hungary after WW2. The closest rings I've seen to this have been German SS officer rings
