Our nose stud sets make great starter sets and this set of 3 studs would also be a fabulous gift idea for a lady in your life with a nose piercing. Each nose stud contains a different 2mm crystal: amethyst, rose and clear. As amethyst is the February birthstone, this set would be particularly well suited to being a February birthday gift. Each nose stud is made from 9ct yellow gold, L-shaped in size and weighs 0.15 grams.
