Your gem would be labradorite, it would be on the back of your neck, and your weapon would probably be a double-edged battle axe. Also you would talk to sea creatures

It looks like a magical egg or something! 

Back of the neck would be great bc it’s the only place my stubby arms can reach lol and I love axes and flails and shit so yessss. Also if this is so I would just chill underwater most of the time and talk to sea life. 

Thank u ❤
