Can't find any info on AJ Mark

(Austin, TX)

I found a ring that belonged to a grandmother of mine that has passed away. It is yellow gold, with what appears to be ruby, or some other red stones around it. It has the marking 14K, and AJ inside. No copyright symbol or anything else, just the AJ. I cant find any information about the hallmark, and found very few other rings online with just the AJ mark. Any help?
