Beautiful Sterling Silver Platinum Plated Mermaid Necklace and Earring Set.
Silver is a metal that tarnishes (oxidizes) quickly. It is also soft and easily scratched. Platinum is just the opposite – it is extremely resistant to oxidation and so hard that it resists wear. So plating a layer of platinum onto silver produces an item of jewelry that is both tarnish-resistant and durable. Platinum also has a bright white sheen that makes silver even more beautiful.
