A permanent necklace that seems to hurt just by looking

Just watching makes me feel pain if I think that my neck is a pierced earring. How was it installed? Even so, the idea is amazing.
Details are as below. It looks like a normal necklace, but it is buried in the neck.

There is a necklace at 360 degrees properly.

If you look closely, your nose is amazing.
