Hi there, l did not know what size my rings were, but wanted to go larger, l went on friday and asked for the next size up l said it was a 14 gauge but they refered to it as a 1.6, and they said that l would be better going to a 2.0 which l did, disapointed as wanted to go an 8 or 6 gauge but they said that l will have to go slowly as nipples dont respond to going to large to quick, hopefully will go to a 2.4 in a couple of months, have had no pain or trouble from them being made larger any advice you could give thanks ron.
