Earrings by Hannah Bedford A glorious grouping of fused 18ct gold and oxidised silver granules seemingly float together to form these contrasting Berry earrings. Features Primary Material : oxidised silver & 18ct gold Fitting Type : Post Dimensions (mm) : 10mm x 10mm x 4mm One of a Kind : No Hallmarked : No Wire Material : oxidised silver, 18ct gold Cleaning InstructionsOxidisation is a surface treatment given to the silver. Over time this can start to rub back, exposing the silver underneath. This is particularly true of rings, as they receive more everyday wear. This worn affect can be very desirable as silver highlights are added to the piece.
