Silver cow necklace with green onyx stone on stainless steel chain 50cm. Pendant is silver plated. Stainless steel is a highly durable metal, allowing it to withstand the wear and tear of everyday activities, which can otherwise damage a ring. The hard metal resists scratches and corrosion thanks to an invisible layer of chromium that prevents oxidation; this makes it a wonder metal of choice for body jewellery. 100% lead free.
