“GAM BR” Gold Hallmark (back to front B)

[aussie1234]

Hello. I’ve come up with absolutely nothing when researching this hallmark myself so reaching out for advice. I’m assuming it’s quite old due to only having to marks and it was an estate piece. If anyone has ideas or resources to help me identify anything about it, it would be appreciated. Thank you.

If anyone has some search tips on how to find out info about obscure hallmarks I’d really appreciate the help. Thanks.

Thanks for the bump. Unfortunately I ended up buying and then immediately returning this ring as the stones were zero % as described, aside from the measurements. I would have loved to know however the quality of the ring was very low. Thank anyway.
