The tanzanite colour CZ crystals in this nose ring are such a vibrant and beautiful shade, it will be impossible not to wow! 7 tanzanite crystals line along the side of the hoop, each one measuring 1mm whilst the hoop itself is 10mm high x 10mm wide x 2mm deep. It can also be worn in a helix piercing and would match beautifully with a pair of simple tanzanite crystal studs or hoops. The gauge is 24 and it weighs 0.1g overall.
