These nose bone nose studs are made out of 9K solid gold with a round clear cubic zirconia stud. The combination of the gold and gemstone is sure to sparkle beautifully. So, this stud is perfect if you want to steal the spotlight. Nose bones are a particularly comfortable type of nose stud as there is much less metal inside the nostril compared to L-shaped or screw style nose rings. This nose stud is 22 gauge/0.6 mm thick, with a ball end to keep the stud secure.
