Great earrings!
These are not waterproof. The glass is like a bead with the chain going through it and the flowers inside it. Surface tension of water makes it unlikely that rain would go inside the glass, but I wouldn't wear them in the shower or while swimming.<br /><br />The red is really visible, just like in the promotional photos. I've included a picture of the earring next to a quarter to give you an idea of overall size. I've also given you a picture of it next to a dime to see that the sphere is about the size of a dime, though my photo doesn't show that well.
