There are many ways to determine if something is made of gold. If the item in question is something like a gold coin or a gold bar one of the easiest ways to determine this is to weigh it. Gold’s density is something hard to counterfeit. You can research the weight of most popular gold coins or gold bars. By knowing its weight in grams it will be easy to spot if the coin or bar does not have the right weight.

If the item is something which the weight can not be research, it is recommended to use an electronic gold tester. Some electronic gold testers are so sophisticated they can not only determine if an item is made of gold, but also indicate the number of karat of gold the item is made of. If an item is made of pure gold it will be 24 karat; if an item is made of seventy five percent gold and a mixture of other metals it will be 18 karat; if an item is made of fifty eight percent gold and a mixture of other metals it will be 14 karat; and if an item is made of forty two percent gold and a mixture of other metals it will be 10 karat.

A mixture of gold and other metals also gives gold some of its different colors. Some examples of this are rose gold which is usually a mixture of gold and copper; and white gold which is usually a mixture of gold and nickel or palladium. Electronic gold testers will usually be able to detect the amount of gold in these alloys. Finding out if something is made of gold is easy if you have the right tools or know the right techniques to do so.
