This pair of hand formed and hand hammered niobium earrings feature an amazing blue color fade. And while they are petite they have an 'attitude.' We create them from 20 gauge (.8mm) surgical grade niobium wire hammered to have a unique look.Then they're anodized in this amazing color fade. They measure 1-1/8 inches (33mm). The ends are de-burred so they will be smooth and won't ouch when you put them on. Niobium is the perfect metal for people with metal allergies.
