Is 925 sterling silver from China true sterling?

Hi,you can check your `sterling silver` jewellery from China with these easy tricks:You may test it with nitric acid. In an inconspicuous place on the item, lightly scratch or scuff a small spot and apply a tiny drop of nitric acid to the spot. Silver plated brass, nickel silver or low quality silver alloys will turn green when a drop of nitric acid is applied because of the high copper content. Sterling will turn a creamy color. If it turns black, it is coin silver. When testing items you suspect may be silver plated, use a small file to cut through any plating or lacquer in a discreet area on the item. If you see a gold color, you can assume it is brass that has been silver plated.Another test is to use a magnet. Sterling silver will not stick to a magnet, but just because the piece does not stick does not mean that it is sterling silver. Therefore, use this only as a secondary test.
