Nice Signetring, but from which time??

[Wolf100]

I´ve got this nice, heavy signetring today. It has some floral cuttings on the sides and four stamps . 800, a crown on the side, a star??? and some triangle. Who knows this stamp and can tell me, from which time this ring could be???

Thanks, Marc

Thanks Götz!! I had a look there, but i found three marks, the 800 of course, the moon like mark and the crown. That indicates germany 1920 - 1940. The last marc, the triangle with some sign in it, i could not find.
