5 Common Ways to Test Scrap Gold - What to Know

Whether you plan to sell or buy scrap gold, you will want to know that you’re dealing with the genuine mineral—however, it’s not always that easy to test the authenticity of gold. Fortunately, there are some ways that you can do to test your precious metals from the comforts of your own home. These ways don’t require any complex processes to complete, while still giving you a good idea whether you’re dealing with genuine gold or not. 

To help you out in this effort, here are five common ways to test your scrap gold and determine its authenticity.

Test With Acid

Before you test the scrap gold with acid, make sure that the acid is in good condition. To ensure its quality, you need to perform an acid test on your test needle kit at least once a month. These tests can reveal whether a specific piece is over or under a certain threshold. 

When testing with acid, rub the piece on your touchstone and make a residue streak that’s a couple of inches long and apply three different acid spots. If you suspect it’s a 14kt piece, a 10kt acid should not dissolve it. Using acids will give you a general idea that a piece is true gold, while simultaneously letting you know the range of its karat value.

Do A Magnetic Test

The simplest test you can do to determine authenticity is through a simple magnet test. All karat quality scrap gold is not magnetic. If the piece pulls on a good magnet, then that means that the scrap “gold” is not real gold to begin with.

Look For A Hallmark Stamp

When testing scrap gold for its quality, look for a hallmark stamp, because this will tell you what the piece is made of. You can find this usually on the clasp of a necklace or bracelet, and in some cases, the hallmark stamp can be found on the inside band of a ring. 

Keep in mind that American-made products are marked in Karat, while European ones are marked with their purity. It’s also possible to. This means that there is a high likelihood of finding pieces that do not have them, especially the ones produced before 1973. 

Check For Spotting or Discoloration

A cursory glance by a trained eye can easily tell you a lot about a particular piece of scrap gold. If it has blackened or greenish spots, then that means that the piece is plated. Worn areas may also indicate that it is only gold-plated—which could make a certain piece less valuable than it appears.

Check Its Weight

Gold is a heavy metal, and it is almost twice as heavy as compared to most other jewelry pieces. If a particular gold-like mineral feels heavy, then there’s a better chance that it’s authentic gold.  


These are some of the most common and easiest ways to test precious metals. When dealing with scrap gold, it’s essential to check them thoroughly before you buy them. The same thing applies if you plan to sell scrap gold. Knowing its quality will help give you an idea of how much it will cost when you sell it in the market. That way, you’ll be able to get the best price for your scrap gold.
