This beautiful 14k solid gold stud earring for cartilage piercings in 16 gauge has a ball screw back for secure fit. The front has a three dot cluster design, but you are able to wear the front and the back interchangeably depending on which direction you insert the post. This post is made for cartilage piercings as it is thicker than the traditional lobe piercing studs. It has the 14k stamp on it!
