chatelaine attachment?

I believe this is an ornamental attachment for hanging on a ladies chatelaine that was worn on the belt. It was recently found in my grandmother’s old jewelry kept by my aunt. There is no pin or hook on the back so that is why I think it is just something ornamental to hang on the chatelaine. My grandmother was from a long line of Farm wives. There was probably no money for the actual chatelaine or fancy watches and scissors. It is silver toned with abalone inlay. Strange for a Nebraska farmer. Possibly a gift from a traveling friend or family member? I know some of the family moved out to California close to the turn of the century. That would make sense for abalone. I love it! I will be searching old photos to see if anyone wore it.
