Handmade and ethically sourced from Bali. Size: One Size SKU: GP495 Plated jewellery, as the name suggests, has a thin layer of precious metal over a base metal (ie zinc alloy, brass, stainless steel). The layer of precious metal is usually between 0. 175 to 0. 5 microns (in comparison, a dollar bill is 200 microns). Since the precious metal layer is very thin, friction between your skin and the plated jewellery can slowly rub off the plating. Also, exposure to water, sweat, soap, perfume and other chemicals can cause the plating to fade. To take care of plated jewellery, you should: Avoid getting it wet with water, soap, perfume, lotion, sweat and other chemicals. If the jewellery does get wet, wipe it immediately with a soft cloth. Store the jewellery in a dry place. Also, it is best to store the plated jewellery separate from other plated jewellery (either you keep them in individual plastic pouches or separate them in the jewellery box). Several plated jewellery in a single bin will rub or scratch against each other and will cause the plating to fade faster.
