All of our earring wires are Sterling Silver or Titanium, then rhodium or 18ct gold plated.
Sterling Silver 925 is the world standard of Silver, used in Jewellery.
Titanium is a silver coloured metal with a very low density, and high stregth. It has a very high resistance to corrosion in sea water, aqua regia and chlorine. These qualitys make it ideal for earing wires and studs.
