These ball earrings are made of real 14k yellow gold (not plated or filled) with a hollow structure and stamped "14K" (585). The hollow structure allows the 14 karat gold stud earrings to be lightweight and comfortable on the ear, as well as making them affordable for a more compelling price. These classic ball earrings are the perfect everyday-go-to earrings. They also make a great choice for those who want to simply put on studs that don't irritate and be the earrings that keep the piercing from closing and keep the hole open to allowing time to heal, as real gold earrings are the ideal choice for sensitive skin.
