The hologram end measures 3mm in diameter.

In our drop-down menus for adding to cart, we show the gauge of the item you are ordering, then the length/diameter, then the ball size if it has any:

Jewelry is measured through a gauge system (conversion chart below). The higher the gauge number the smaller the wire is. For reference, a standard "earring" is usually 20 gauge. Jewelry gauges can vary between manufacturers. There is no universal regulation on companies to make a standard size in body jewelry. This is because some jewelry is made outside of the USA and measured in millimeters. And in the USA jewelry is measured in inches.

Rings

Rings are an essential item that can be worn in many piercings. They come in various styles:
  • Captive bead rings - These use tension to hold a bead in place.
  • Clickers - These use a hinge to open and close the ring.
  • Segment rings - These have a "segment" that comes completely out of the jewelry similar to removing a bead. But it looks like a completely seamless piece of jewelry.
  • Seamless rings - These rings require bending to open & close.
How to measure rings

Verified purchase 20g 7mm Gold
Looks and feels great in my nostril piercings, although I wish Halftone would use a longer-lasting adhesive because the gem in one of my nose screws fell out of the setting after only four days of wear. Bigtime shoutout to BAF customer service though, for seeing my original review about the gem falling out and reaching out to offer a credit. This is why I keep coming back to BAF!

Bought as a gift for a friend - this is her go-to jewelry for her nostril because the black metal and opal-like stone look perfect together and match her alternative-grunge style well.

Love these! Fronts are big and make for a great statement piece. Just wish the tails were a bit longer.
