Hypo-allergenic yellow gold color Niobium and steel silver color certified surgical implant grade Titanium ear wires are suitable for metal sensitive wearers.
Niobium is not plated or painted. It is anodized, meaning it is colored by dipping it into an electrically charged “bath”. Because it contains no nickel, most people with metal allergies can safely wear Niobium.
Titanium is good for metal sensitive people with newly pierced ears. Titanium is typically not anodized for ear wires.
When you attach them to the earring, remember to bend the jump-ring only enough to get the ear wire on. Twist the ring, rather than opening it out, to avoid overworking the stress point, as shown in photo.
