Classy piercing rings made in sterling silver, black niobium or gray (natural) niobium with a freshwater pearl that works as a captive bead.
On the second last picture you can see sterling silver together with black and gray niobium, it's from another listing and just to show the difference between the metals.
You can choose between an inner diameter of 8mm, 10mm or 12mm. The wire thickness is 1mm (18g), 1.2mm (16g) or 1.6mm (14g).
The pearls measure between 3.5-4mm, I try to match the pearl with the size of the ring but just write me in the comments if you prefer a smaller or larger pearl.
