My mother pierced mine back when I was 16 and then for years I wanted a 2nd set of holes. Don't know why and after getting the 2nd set done I can't remember why I wanted them. It also means that I now have to buy 2 sets of ear rings for them.
When my mother was handing out her jewelry as she no longer wanted them, I got the diamond studs cause my older sister didn't have pierced ears at the time. Since them she has had them pierced but she waited till she was in her last 50's to get them done. Now she's eyeing the diamond studs.......:-)
