Belly Button Piercing Jewelry It's usually made of titanium, which lessens the chance that you'll have an allergic reaction to the metal. It should be thick enough (around 14G [gauge]) to lessen the chance that your body rejects it.

Most professional navel piercings are done in a standard 14g (gauge width) and pierced to fit the standard size 10mm and 11mm belly bars.

The reason we choose gold, platinum, or titanium as our metals of preference for your belly piercing is that these materials are more pure and tend to have fewer additives that your body can react to.

Custom Size Belly Bars Below we have a growing range (pardon the pun) of resizable belly button rings - available for adjustment to anything between 6mm in length up to 19mm in length for 14g bananabells.
