Add to your aurora borealis collection with this pretty opal nose ring. It has three natural opals along the side, with each one measuring 2mm whilst the hoop itself is 10mm high x 9mm wide x 2mm deep. Due to the natural nature of opal, colour will vary with each stone. Weighing 0.1g, it has a gauge of 24ga which means this can be worn in a helix piercing as well.
