This is a helix stud earring which was inspired by elements in gothic architecture.
This earring is made of gold-plated silver and has a nice matte finish.
It is held by a hole on the top of the ear and comes with a gold plated silver ear backing.
I have added a picture ( last one ) with the place of the piercing colored in black that fits the piercing.
It's sold as a single ear piercing and fits both ears.
The length from side to side is 0.9 inch ( 2.4 cm ).
The width in the center is 0.27 inch ( 7 mm )
The post that goes in the ear is 19 gauge ( 0.9 mm )
The earring is "made to order" and takes 1 - 3 weeks to make.
