My e-ring is set kinda high, so I keep knocking it against things accidentally. Today, for instance, I've knocked it 4x already. So far, I don't see any obvious damage yet, although I don't have a magnifying glass. After reading some of the previous messages about people getting their diamonds chipped/broken, I'm terrified. Should I just stop wearing my e-ring? How likely is a diamond to chip or crack? Thanks!
