Earrings by Hannah Bedford Inspired by Sea Urchins, these silver spine earrings form a contemporary structure, which is meticulously embedded and scattered with gold granulation. The contrasting oxidised silver and gold create a dramatic aesthetic. Features Primary Material : 18ct gold and sterling silver Fitting Type : Post or Stud Dimensions (mm) : 12x4x8 One of a Kind : No Hallmarked : No Wire Material : sterling silver Cleaning InstructionsOxidisation is a surface treatment given to the silver. Over time with wear, this can slowly start to rub back, exposing the silver underneath. This worn affect can be very desirable as silver highlights are added to the piece. However if you would like the oxidised finish to be restored Hannah can provide this service.
