PVD titanium or 316LVM surgical steel N/A External 10.5mm star Lobes, helix, tragus, and more! Each piece is sold individually. The Stacked Stars Cartilage Stud is a high-quality piece designed 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 Stacked Stars Cartilage Stud is 316LVM surgical steel or PVD titanium! 316LVM surgical steel goes through a process called low carbon vacuum melting. The process sucks 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 is more durable and therefore lasts longer than gold traditional plating. If you have sensitivities, we recommend our steel, anodized, blackline, or untreated titanium jewelry instead. Blackline is a titanium carbide PVD coating. PVD stands for Physical Vapour Deposition. In other words, the titanium carbide deposits onto the metal as a vapour. As a result, the titanium looks black. This coating is hypoallergenic. This piece is 16g. 16g is the standard size for a cartilage piercing if you were pierced with a needle. However, if you were pierced with a gun, your piercing may be too small for this. You can shop our for options that will fit you. This stud is a favourite for cartilage piercings (like we said before). Here are a few examples: helix, tragus, flat, and even ear lobes!
