It is a single cartilage earring in shape of a moon, with a harmonic intertwined Celtic design.
It is made of solid sterling silver, nickel free.
The length from side to side is 0.86 inch ( 2.2 cm ).
The width in the center is 0.35 inch ( 0.9 cm )
The post that goes into the ear is made of 19 gauge ( 0.9 mm ) wire.
It is held by a hole on the top of the ear and comes with a silver ear backing.
I have added a picture ( last one ) with the location of the piercing colored in black that fits the earring.
It comes as a single ear piercing, and fits both ears.
This is a "made to order" jewel and takes 2 - 3 weeks to make.
