this 9ct white gold and 0.05ct diamond single stud earring will prove that diamonds really are a boy's and girl's best friend. weighing just 0.25, the i colour diamond is 3mm x 3mm x 3mm. the front to back distance of the earring is 12mm and it comes marked with a 9k metal stamp. this earring is sold as a single stud so would look great in a second piercing or perhaps get two to wear as a pair!
