    Magnet

    This test is not full proof but will tell you that the gold is real. You need to use a stronger magnet for this test. If your gold object sticks to the magnet than it is not pure. It might be gold plated or may be mixed with some other magnet.
    However, it fails to attract with the magnet then you still cannot guarantee that your gold is real.

    Glass

    You can test whether your gold object is pure or not with a piece of glass. Rub the gold object to the glass and if it leaves scratch marks then the gold is not pure. However, if it leaves the glass scratch less then it still may not be pure gold.
    Note that you should not use a valuable piece of glass. You can use an old glass or unused frames of picture for this test.

    Unglazed porcelain tile

    Unglazed porcelain tiles can be used to determine whether gold is real or fake. You simply need to scratch the tile with gold and check what colour marks are left. Your gold object is real if you see marks of yellow colour. However, if you see black or grey then your piece of gold is not pure. Your gold piece may be gold plated.

    Use fine metal file

    You can check whether your gold object is pure or not by filing a small portion of it. If you can easily file a small section then the piece of gold is pure but if it takes time then it is not pure gold.

    Acid test

    First buy hydrochloric acid from any hardware store and then take protective measures to conduct an acid test on goal. Dip cotton swab in the acid and drop small amount of acid on a small area of gold which is filed. If the piece of gold is pure then no acid can do no harm but if it breaks then it is not pure.
