Что такое 925 Серьги с покрытием из стерлингового серебра?
Покрытие серебром или золотом — это процесс с использованием электричества, при котором на основной металл наносится слой серебра или золота толщиной в микроны..
It will flake off with wear exposing the base metal underneath, usually nickel, латунь, copper or a similar alloy.
Plating on earrings isn't usually a big deal because they don't come into much contact with the skin, like a necklace, ring or bracelet would. As long as the ear wires are a solid hypoallergenic metal you should be fine. So if earrings are silver plated but have sterling silver ear wires you're pretty good to go and won't notice much wear on the plating.
I don't suggest buying earrings with silver plated ear wires though. The plating will wear off in a couple of weeks and leave you with a low quality metal exposed to your sensitive ear holes. Если у вас аллергия на металлы, это может стать большой проблемой..
