Vintage earrings with the solar system

I love this. Extremely creative and different. These earrings have a floating solar system. I've never seen anything like this. This copper color solar system is surrounded by stars and moon floating around it...WOW Currently they are clip earrings, but you 'could' cut off the glass top part, and add one of your wire loops! I don't know what era is from, they were my grandmother's, and it's very special! I don't know what she paid for them but back in those days...LOL
