I am not sure why these earrings got any bad reviews, I got them in white gold , 45 millimeters and I am quite happy with them ! I am going to order them in yellow gold as well . They are heavy enough as not to fall out of the ears , under normal conditions . I would not wear them while running or working out , just because the bouncing action COULD cause one of them to get shaken out of the ear lobe , but otherwise they seem quite secure . I would not hesitate to get them , as I said , I am going to order them in yellow gold too  !!
