Help Needed with Hallmark

[Ajzyk]

Hello,

this is assumed German Ring from the early 20 centuary.
Can anyone tell the maker's name? or specific region/era?



Thanks
AJ

the maker's mark is reminiscent of early art deco with a bit of art nouveau still softening the letters. A.G means aktiengesellschaft, as in limited company.
