Cut small and set close to the skin, so it shares a lobe with whatever else is already there. Choose any letter, A to Z, with the one exception of Q. The stud fitting means a healed piercing, and a lobe you do not think about twice.
The Letter stud is a 5 mm initial in 14k gold, pavé set with natural white diamonds, for a healed lobe.
Wear it on its own, or against an Ephyra stud on the same lobe.
