The best way to test whether a piece of jewelry or other item is real gold is to take it to a reputable jeweler and have them test it. If this, however, is not an option, this guide on how to test for real gold will introduce you to some methods of quickly and easily testing an item to see if it is made of real gold.
Buying gold can be a challenge, since it is difficult for laymen to determine whether an item is real gold or not. When buying online, second hand or from an unfamiliar seller, one cannot always trust the retailer. If you are concerned whether an item you own is real gold or not, try some of the tests below to find out. Be aware that the easy gold tests mentioned below are not 100% accurate, so if you want to be completely sure if your item is gold or not, take it to a jeweler or get yourself a testing kit.
VIDEO | How To Test Gold Purity Using an Acid Testing Kit
This video posted to YouTube by user SellingYourGold gives a step-by-step demonstration on how to test for real gold using a mail order acid testing kit. The box that arrived contained one page of instructions, a test stone and some bottles of acid. There were acid testing solutions for platinum, silver, 10 carat gold, 14 carat gold, 18 carat gold and 22 carat gold. The instructions start with taking the stone and rubbing the jewelry on the stone backwards and forwards at least twice which will leave some of the metal behind on the stone. Then some of one of the acid testing solutions is placed on the stone. If an acid rated at a higher carat is placed on a metal then the color will change, but if the testing acid and the gold carat are the same, the color will stay the same. If, for example, the user places 18 carat rated acid on 14 carat gold, the color will change, but if 14 carat rated acid is placed on 14 carat gold then the color will not change.
Easy Gold Tests
The best and most reliable way to test whether an item is made of real gold or not is to take it to a trusted jeweler and ask them to test it for you. Depending on the jeweler, they may perform the test for free or a nominal fee. However, if this is not an option, try one or more of the following tests, but keep in mind that they are not 100% reliable:
Look for a stamp: Most gold jewelry will be stamped with a "hallmark," which corresponds to its carat (24k, 18k, etc.) However, keep in mind that some counter fitters may use fake hallmarks to pass their items off as real gold. Also, if the item is lacking a hallmark, it does not necessarily mean that it is not gold—if the item was repaired or resized, the hallmark may have been removed in the process
Eye it out: Look for discoloration, especially near any areas where the item may be subject to friction, such as near chain links. If the item is plated, this is where the plating is likely to rub off, so if you see areas that are a different color than the rest of the item, it is likely not real gold. Also, if you have had the opportunity to wear the item and it has discolored your skin, it is not real gold
Softness test: Real gold is relatively soft compared to other metals. If there is a place on the item on which you don't mind creating a small imperfection, such as the inside of a ring or the underside of a clasp on a bracelet or necklace, poke it with a pin. If the pin breaks off or is met with strong resistance, the item is likely not gold. However, if the pin sinks into or makes a dent in the item, it may be made of gold
Magnet test: Hold a magnet near the item to be tested. Real gold is not magnetic, so if the item sticks to the magnet or if you feel a pull toward the magnet, the item is likely not gold or is an alloy that contains very little gold. Keep in mind, though, that if your item does not appear to be magnetic, this doesn't guarantee that it is gold, since many items are not magnetic

The best way to test for gold is to have it examined by a professional. The easy gold tests described above should only be used to give you a general idea of whether your item is real or false gold. If you want to be certain, you will likely have to spend some money and either buy yourself an acid testing kit or have a jeweler test the item for you.
