Hallmark question - Gold ring

[zachary898]

I got given a gold ring and im unsure with some of the hallmarks and can not find any information on them.

The markings are 375 which i understand and ZRE & AGR.

Any help would be appreciated

375 is 9 carat gold, or 37.5% gold

ZRE and AGR would then be the maker's mark of the jewelling company that produced it.

Pictures might help too
