These piercingrings are made from pure niobium that I heat up to make black. The ornament/lock is handcasted in sterling silver after a prototype that I made, oxidized to bring out detail and then polished.
I make these rings in 1mm (18g) 1.2mm (16g) and 1.6mm (14g) with an inner diameter of 8mm, 10mm och 12mm. In 18g the ring is a twist open ring where the ornament hangs of the ring. In 14g and 16g the ornament is a captive bead that "clicks" in.
