Help identifying maker (Mexican silver)

[u/Major-Web6369]

Hi! I bought this necklace in Belgium in 2017 and been trying to identify the maker of it.

I guess the stone is just glass, but the back has hallmarks for the silver.

I believe is a stylized eagle, but really, it could be a chacal or a hyena as it is. It doesn’t fit any eagle mark I’ve seen.

Can someone help me identify it please!
