Setting gemstones in SS balls

Hey,

i’ve got a questions for the body jewelry manufacturers out there…
or for anyone else who would know… i’m wanting to make some
Gemstone barbells… they’re 4mm gems set in a 6mm Stainless Steel
ball… i’m guessing i would go about doing this by using a 4mm stone
setting bur to get the place for the stone to be set, but i’m kind
confused on how i would actually keep the stone in there… is it
just set in there with pressure? or is it glued in? i’m not exactly
sure how others are doing it, please let me know any info you have…
thanks!!!
