Opal Brooch 10K

I’ve never seen anything quite like this, it was my grandmothers, and my mom has asked me to sell a few of her things for her. I researched the markings for hours and couldn’t locate anything like them so if anybody recognizes them or has any information it would be appreciated. I’m fairly certain it’s 10 karat gold based on the marking in the last photo there is no damage to the pan and is still in working condition, I’m pretty sure that the bar pan holds a crystal, the opal is spectacular and mint condition. It really has a lot of fire to it. Hard to capture in photos.
