This rich green opal stone makes for something a little different from the standard clear crystal style nose studs! A beautiful shade of forest green mixed with hints of gold, the opal itself is 2mm whilst the actual nose ring is 10mm wide, which also makes it possible to wear in a helix piercing. Weighing just 0.1g, it's lightweight and easy to wear, with the coil closure meaning you just pull the wire out and insert back in to secure it in place.
