A Nostril Stud is a piece of jewellery worn in a nosepiercing, anywhere on the surface of the nose. There are different designs of nostril studs, which include 'hook' studs, straight micro studs and nose rings.
A hole is pierced through the skin and cartilage of the nostril. A nose stud or ring is inserted through the hole.
Titanium is a light, strong, lustrous, corrosion-resistant transition metal with a white-silvery-metallic colour.
