Silver is a precious metal. People consider it a cheap product because of its low price when compared to Gold. People who think about purchasing jewelry for a low price will choose plated designs which make a good choice. Naturally, 925 is a common notion used to indicate sterling silver since it establishes a percentage (92.5%) of the original quality metal present within them. But sometimes, to provide a unique edge to the model, the shopkeepers name them as 926 collections or any other name.
