Pretty in purple, this opal stone is a rich purple colour with subtle hints of deep blue. The opal itself measures 2mm whilst the hoop is 10mm high x 9mm wide x 1mm deep. The spring coil closure makes it very easy to insert/remove, just pull the wire from the coil and then pop back in to securely fasten in in your nose. Weighing just 0.1g, this makes it both light and comfortable to wear.
