PVD titanium or 316LVM surgical steel N/A External Lobes, helix, tragus, and more! Each piece is sold individually. The Plain Circle Cartilage Stud is a high-quality piece designed especially for cartilage piercings. Put this stud through your piercing from the front and screw the bead on. The bead is more secure and comfortable than a traditional earring with a butterfly backing. The Plain Circle Cartilage Stud is 316LVM surgical steel or PVD titanium! 316LVM surgical steel is a low carbon vacuum melted. The process sucks the nickel out of the steel. Nickel is one of the most common causes of metal allergies. This process cannot remove 100% of nickel. As a result, a small number of people react to it. We recommend our anodized, blackline, or untreated titanium body jewelry if this is a concern for you. PVD stands for Physical Vapour Deposition. In other words, the colour deposits onto the metal as a vapour. As a result, the titanium looks black, gold, or rose gold. Blackline is a titanium carbide PVD coating. This coating is hypoallergenic. Yellow and rose gold coatings may cause reactions. This stud is a favourite for cartilage piercings. Here are a few examples: helix, tragus, flat, and even ear lobes!
