Submitter's Comment
Look for a stamp. Items advertised as silver and sold internationally should be stamped based on its silver content. If there is no stamp, be leery. It may be still be pure silver, but created in a country that doesn't require stamping.

Evaluate the international silver stamp rating. Look at the silver piece with a magnifying glass. International sellers of silver will stamp silver as 925, 900 or 800. These numbers indicate the percentage of fine silver in the piece. 925 means that the piece is 92.5 percent silver. A stamp of 900 or 800 means the piece is 90 percent or 80 percent silver, and is often called "coin"

Method Two of Six:
Testing Magnetic Qualities

Test with a magnet. In particular, use a strong magnet, such as the rare-earth magnet made out of neodymium. Silver is paramagnetic and exhibits only weak magnetic effects. If your magnet sticks strongly to the piece, it has a ferromagnetic core and is not silver.
Keep in mind that there are a few other metals that do not stick to a magnet and can be made to look like silver. It is better to perform the magnetic test in conjunction with another test to make sure the core is not another metal.

Try the sliding test. If you are testing silver bars, there is another way you can use a magnet to see if your silver is real or not. Angle one of your silver bars so that it is at a 45 degree angle. Slide the magnet down it. The magnet should slide slowly down the face of the bar. This may seem counterintuitive, but silver is paramagnetic and the rare earth magnet induces electric eddy currents in the silver which act as an electromagnet to create a braking effect that slows the descent of the magnet.

Bleach Test

1
Simply put a drop of bleach on your item. Silver tarnishes extremely quickly when exposed to a powerful oxidizing agent such as common bleach.

2
Watch for tarnishing or no reaction. If it rapidly tarnishes and turns black then the item is silver.

Note that silver plated items will pass this test.
