Tragus piercing earrings go through the cartilage rather than the lobe, so the post is shorter and thinner than on a standard earring. All 11 pieces here are built on 925 sterling silver, some with gold plating over it. Most use Majorica pearl, while Scarlett uses an 8 mm natural freshwater pearl. Jenny, Anja, Shelly and Aria each come in silver and gold, so matching the metal to whatever else you already wear in that ear is straightforward.
