Well, it's hard to see both earrings at once, actually, even looking straight on.
I have a pair of earrings that my grandmother made out of an old 1920's watch. You know, the type with the black cord as a strap. The earrings were the gold accents on either side of the watch face. It turns out they both go the same way, instead of mirror image, so they look different on each ear. Nobody has ever noticed.
On a separate note, those rice krispy earrings are a very interesting design. I like them, too.
