GOS is Gold over Silver. Gold-plated sterling silver jewellery is the best and most valuable in the gold-plated jewellery category. Designer jewellery and fine jewellery are mainly made from gold over sterling silver. The quality of the gold matters as does the silver. The reason we plate Gold over Silver is due to pure gold being too soft for jewellery and is alloyed with a base metal (silver) for strength.
