Testing my Scrap Gold at Home

DIY Tests for Scrap Gold Jewellery

Gold is valued according to the carat system which most commonly has measurements of 9c, 14c, 18c, 22c and 24c.  18c gold is 18 out of 24 parts pure gold, which means it is 75% pure gold (18/24 x10).  Jewellers have specialist equipment which measures the percentage, and therefore the carat, of gold in a piece of scrap jewellery.

Easy Ways to Test Your Scrap Gold At Home

Other than looking for a hallmark, there are no quick and easy DIY tests that you can conduct at home to determine the carat of your gold, but there are some which can indicate whether or not your scrap gold is in fact gold at all.  Here are 3 DIY gold tests:

  1. Skin Test

Gold is an inert element and will not react with chemicals it comes into contact with, where as fake gold will. Hold the jewellery in your hand for a few minutes.  The sweat from your hand will react with the piece and if it’s fake your hand will discolour slightly.

  1. Float Test

Gold is heavy and will immediately sink to the bottom of a glass of water once you place it in there.  Fake gold will float, or hover just off the bottom of the glass.

  1. Vinegar Test

Place your scrap jewellery in a glass of white vinegar and leave it to sit for 15 to 20 minutes.  Remove the piece and rinse it off with water; if it changes colour it’s fake, if it remains shiny and retains its colour, it’s real.
