They're about actual size of the picture, normal size for any stud earring.  The silver is polished beautifully and they truly stand out against any skin tone.  I bought these for my bridesmaids with matching necklaces and they were beautiful on all.  Great as a gift or a treat for yourself.  If you have more than one piercing in each ear, they offer dangle earrings that match and would look great as well.
