Neodymium Rare Earth Magnet for Testing Scrap 9ct 18ct 24ct Gold,Silver,Coins & Antiques half full sovereign

It does what exactly says and I have tested my copper bar it was effective because it slides slowly off of my copper bar which meant it was real copper bar.

very good accuracy magnets

A magnet of good strength, but could have brought the same cheaper without all the unnecessary packaging.

Ok very small size

It tests on silver and gold. But when gold or silver covered stainless steel, the magnet does not react to this, giving the impression that it is pure gold or silver.
