We love a bit of sparkle but are totally enchanted by the soft, lustrous glow of the natural moonstone used in this beautiful belly bar. The 4mm, round gemstone sits in the 5mm securing ball section below the star shaped upper portion. The bar which screws into this is suitable for 15 gauge belly piercings and is 13mm long. It's worth mentioning that due to the natural formation of the moonstone, it may differ in colour from the picture.
