The polished gold ball stud is one of the most enduring earring forms in fine jewelry for a reason that is impossible to argue with: the sphere is perfect, and in warm polished gold it reflects light omnidirectionally with a brightness that rounds any face and suits any occasion. At approximately 5/16 of an inch in diameter, these 18K yellow gold over sterling silver studs sit on the earlobe with a presence that is visible and warm without being bold or statement-making. This is the earring you wear when you want to look exactly right with minimal decision-making. Push-back closures. A piece that belongs in every jewelry wardrobe.
