Why settle for just one coloured crystal when you can have a whole spectrum of colours in one with this iridescent, aurora borealis stud! Held in a sterling silver claw setting, the 1.5mm cubic zirconia shimmers with different hues depending on the light, matching those seen in the northern lights. A 24 gauge straight pin sits directly behind this, allowing you to achieve a bespoke fit and therefore supreme comfort, making this an ideal choice for 24/7 wear.
