Aquamarine is such a pretty colour, it's not just for March babies! Each crystal is 1mm, and the hoop itself is 10mm in diameter, with a gauge of 24ga (this is the thickness of the part which goes through your nose). All of our studs and hoops are lightweight but this one is in particular, weighing just 0.1g. Light blues are perfect for adding a little bit of colour to your everyday jewellery look.
