This is a delicate faux nose ring, inspired by Celtic designs. It's made of sterling silver. It hugs the nose and doesn't require a piercing. You slide it on from the bottom of the nose, and then you can close it a little so it will hold firm on the nose..
The size of the nose stud is - 0.15 \ 0.3 inch ( 0.4 \ 0.8 cm )
