This stunning labret has a cubic zirconia star stud which is held in a 14-carat gold base. The labret bar is made of bio-plast, a bio-compatible plastic which is perfect for people with metal allergies. It is also very comfortable to wear since it is slightly flexible. Another advantage of bio-plast is that it can be cut to any length you want, so these labrets are sure to fit perfectly. They are 16 gauge/ 1.2 mm thick which will suit multiple types of piercings. Although most people usually wear labrets in lip piercings, they can also be worn in ear cartilage piercings. Such as: tragus, helix and flat piercings.
