How to test for Fake Silver?

How do we test for real or Fake Silver?

When we buy precious metals, we want to make sure we get the real, authentic metal. There are many good ways to test for real silver.

Magnet Test

One of the easiest way is to use magnet. Silver and gold are diamagnetic (metals that are not attracted to magnets) and a magnet will not stick to it. Any metal that sticks to magnet is definitely fake.

And real silver has an interesting reaction to magnet. When you move a magnet over the surface of a silver bar, you will feel a small resistance, as real silver is paramagnetic and create electromagnetic waves that resists the movement.

Ice Cube Test

Among all the metal, silver is the best conductor of thermal energy. It conduct heats extremely well. If you place an ice on top of a real silver coin, it will melt immediately, as if it is on a hot surface.

Sound Test

Strike your silver bar with another metallic object. If it is a real silver, you would hear a ringing sound that holds for 1-2 seconds. If the sound is non-ringing or a strange dull sound, please be cautious.

Density Test

Get an accurate scale and note the weight of your silver bar.

Get a glass of water, place it on the scale, and set the scale to ZERO.

Tie the silver bar, dip it COMPLETELY into the water, but without touching the base of the glass. The silver bar should be in the middle of the water, note this new weight number on the scale.

Divide the first weight of the bar, by the 2nd weight number (in the water), this number should be 10.49 for an accurate measurement of Silver density. (Silver Density = 10.49 g/cm3)

Ultrasound Test.

Using special instrument, you can use an ultrasonic device to test for consistency in a bullion bar. Sound waves travel at different speed through different metal. If your silver bar is merely silver plated, the numbers would differ from a pure silver bar of 99.9 purity. The sound velocity for pure silver should be 3600 meters / second (or  0.140 Inch/µSecond)


Caliper Test

Many established brand mint has known dimension and tight tolerance levels. For example, a silver Panda coin of 1 oz would have a diameter of 40.0mm and a thickness of 2.98mm. An American Silver Eagle 1 oz has a diameter of 40.6mm and a thickness of 2.98mm Calipers can reveal any inconsistencies in dimensions, and you should refrain from buying such items.

Acid Test

Warning: This test is destructive and will spoil a tiny portion of your silver. Please do not use unless absolutely necessary.

Buy an acid test kit, it is commonly sold on Amazon. Scratch a surface of the silver bullion and add a few drops of the acid on the silver. If it is pure silver, the color would be Bright Red. If it is silver, but not pure, it would be dark red, brown or green. Any other color means it has no silver in it at all.
