L-shaped studs are always a popular choice due to how easy they are to insert, and this 9ct blue opal stone stud is no exception! Featuring a 2mm natural opal, the colour can vary with each individual stone but all will display a deep, rich ocean blue colour with subtle hints of green. The pin length is 8mm and it has a gauge of 24ga which refers to the thickness of pin. Weighing just 0.1g, it's really light which means it's super comfortable to wear!
