With gold prices spiraling upwards, it’s critical to make sure that the jewelry you are considering purchasing is real, and made of solid gold. And this undertaking can be even more mysterious when inspecting white gold jewelry. Taking your gold jewelry to a local jewelry store is the most convenient way to know your gold is legit. Luckily, there are a few proven ways of checking the gold content of your jewelry yourself.

The first method is by using acid. As a jeweler is testing your gold jewelry, they use very specific acids of certain strength, and the stronger the acid is, the better it’s able to dissolve away at the more purer alloys of gold. Since you aren’t able to measure something that accurately, you can merely use nitric acid. First make a minor scratch on the jewelry with a file in an area that will not be too noticed . Then using a dropper, apply a couple drops of nitric acid. If the jewelry is merely plated, the alloy inside will turn color or bubble as the acid dissolves it . If it’s real gold, there will be no chemical reaction . For gold chains, it’s often easier to test on the clasp at the end of the chain.

The second approach is by inspection . Simply hold it in your hand and feel the weight. If it feels heavy, there’s a good chance it’s gold or platinum. On the other hand, silver alloys weigh approximately 70% that of gold, so if it’s gold plated silver, it will be a noticeable difference. Tungsten is roughly the same weight of 14 karat gold , however tungsten is a darker gray metal.

The third method is to check the jewelry to see if it is stamped and hallmarked. Gold Jewelry must be stamped either in it’s purity form, or it’s karat grade. Karat grades commonly used are 10K, 14K, 18K, etc. Because pure gold is 24 karat, to get the purity you simply divide by 24. And then you just multiply by 100. So 14K is 14 divided by 24 times 100, which is 583 (or sometimes written as 585). Likewise, 18 karat gold is 750.

Tips: Be cautious when buying gold jewelry from websites such as Craigslist. If you decide to purchase something from a stranger, ask them to meet you at a jewelry store. It’s safer, and you can ask the jeweler to check it if you have any doubts. Also look for a second stamp on the jewelry near the karat grade. This is from the actual producer of the jewelry, also called a hallmark. Higher end gold jewelry tend to have the manufacturers logo which would allow you to trace back the origin of the jewelry. Therefore you can feel more confident you’re buying an item that was stamped accurately.
