Both jewellers and jewellery enthusiasts believe that gold has distinct properties that can be identified only through thorough examination.

This blog will discuss ways to help protect you from goldsmiths who are engaged in questionable practices. We encourage you to read on so that you can tell the real value of gold.

The Stamp Test.


Make sure that you check for the Gold Jewellery Stamp (GJS).  This has to be accompanied by the Jeweller’s Stamp of Approval as well.  The GJS is a small stamp that marks the purity or the karat of the jewellery.

However, you need to be extra alert, as there are document forgers who can easily recreate these stamps. So, if you see either a Heavy Gold Plate (HGP) Stamp or a Heavy Electroplated Gold (HEG) Stamp, walk away. What they’re selling are either fake or ‘gold-filled.’

The Acid Test.


Make a tiny scratch mark on your jewellery and drop a small amount of liquid nitric acid onto the same spot. If it turns green, then, obviously, it is fake. If the spot turns a bit milky, on the other hand, then what you have is a gold-over-sterling silver piece. If the tiny scratch mark didn’t change at all, then your gold jewellery is real.

The Magnet Test.


Real gold are non-magnetic. For this test, you will need a stronger than average magnet. If the magnet attracts your piece of jewellery, then it is obviously fake. With the exception of plated clasps, of course. Some jewellery clasps can be magnetized. The links and the charms, on the other hand, should not be so.

The Float & Rust Test.


Drop your gold jewellery in a cup of water. If it floats, then it isn’t real. Also, fake gold shows signs of rustiness following exposure to an excessive amount of moisture. However, if it stays at the bottom of the cup, then you are assured that your jewellery is the real deal. Simply because, genuine gold is heavy and not prone to rust.

The Skin Test.


If you see either shades of black or green on your skin while wearing your jewellery, then your piece is fake. Gold jewellery is typically mixed with other precious alloys; however, the purity of gold must remain in each piece for it to be authentic.
