i have a high scool friend whos family has also been a long time family friend who owns a jewerly business
ive taken advantage of this over the years when it comes to buying jewerly for me and my wife

my wife has 14 lobe and cart piercings and has a pair of studs for each
her biggest pair is 1.5, then about 1, .75, .5, then the rest are all between .1 and .25
