Tourmaline is the birthstone for October, and the depth of pink varies with each item of jewellery. In this particular nose ring, it's a deep, dark pink rather than pale, and each crystal measures 1mm with the hoop itself measuring 10mm high x 10mm wide x 2mm deep. The gauge (thickness of the part which goes through your nose) is 24Ga and the overall weight is 0.1g, so it's super lightweight and comfortable to wear.
