Description You are looking pretty sharp in our Tack Stud Earrings. These tiny but mighty studs add some cool factor to your ear lobes. These earrings are sold with 18K backs. The increased alloy content in 18K gold earring backs allows them to endure more friction and stress associated with daily wear and removal of earrings. For those with metal allergies, we sell 22K earring backs separately here.
