With gold prices rising every day, it’s more important than ever to make sure that the jewelry you are buying is made of real gold. And this task can be even more complicated when evaluating white gold jewelry. Taking your gold jewelry to a local jewelry store is the easiest way to ensure your gold is real . Luckily, there are a few ways of checking yourself that the jewelry is solid gold.
The first method is by using acid. When a jeweler tests gold, 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 small scratch on the jewelry with a file in an area won’t be too visible. Then using an eye dropper, apply a couple drops of nitric acid. If the jewelry is only plated, the base metal underneath will change color or bubble as the acid dissolves it . If it’s made of gold, there will be no chemical reaction . For gold chains, it’s often easier to test on the clasp .
The second approach is by inspection . Simply hold it in your hand and feel it’s weight. If it feels heavy, there’s a good chance it’s gold. Silver alloys weigh approximately 70% that of gold, so if it’s gold plated silver, it will be a noticeable difference. 14 karat gold and tungsten do have the same density and weight feel, however tungsten is a darker grey 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. Common karat grades are 10K, 14K, 18K, etc. Purity is a 3-digit number calculated by the karat divided by 24, since pure gold is 24 karat gold . 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 careful if purchasing from Craigslist . If you decide to purchase something from a stranger, ask them to meet you at a jewelry store so the jeweler can inspect the item in question. Also check for a second stamp on the jewelry near the karat grade. This is from the actual producerof the jewelry, also called a hallmark. Nicer pieces of jewelry tend to have the manufacturers logo and can be traced back to where it was made. Therefore you can feel more surefooted you’re purchasing an item that was stamped with the correct karat grade .
