The butterfly itself is 3/4 by 1/2 in. (fits inside a nickel)The bead is 4mm -The earring wire (is thin and light) just a standard earring wire. I have a better photo, but I don't know how to add more photos after my ad is already posted. Any ideas? From now on, I'll post any photos with a quarter in the photo. Sorry. It's is pretty and not heavy. I've given these as gifts to my nieces and cousins and they're from 5 years to adult.
