Button
Round from the front, flattened from the side. The standard shape for stud earrings.
A button pearl is a squashed sphere: circular in outline, compressed through its depth.
The flat side sits flush against a post or a setting, so the pearl stays put and does not stand awkwardly off the ear.
Because they are less desirable in strands, buttons cost less per millimetre than rounds while presenting an identical face.
When you are buying
For studs, button is the right shape and a round pearl is money wasted. Nobody sees the back of an earring.
