Beginner’s Guide to Examining Authenticity of Gold or Silver

Gold and silver are some of the most valuable metals in the world. They cost a great deal of money to buy. In fact, they are highly valuable that they are considered investment pieces (their value also increases with time). Nowadays, gold is used for making jewelry and other related items. If you are planning to buy one for yourself or a loved one, it pays to test silver bullion and gold so you do not end up buying a fake one.

Detecting a fake gold or silver is easier said than done, though. Unless you have a skilled eye, you probably won’t be able to tell a real gold versus a fake one when you put them side by side. Thankfully, you can now eliminate the guesswork with gold testing equipment sold in the market. This type of equipment provides you with the ability to determine a real gold from a fake one.

There are a variety of procedures and methods used in testing gold. Take time to learn about each method so you will know how to test gold and silver at home. The more common and one of the first few ones to come out in the market is the acid testing kit. The kit will provide you with multiple vials containing different types of acids. Depending on the reaction of the acid to the gold, you will be able to tell how much karat a gold contains. You can also use this same method to test silver bullion. You will know if the metal is authentic because the material will be dissolved upon contact to the acid, leaving you with pure gold.

Another testing method used in the earlier days requires the use of a touchstone. This is a rough black stone that is rubbed against gold. When you rub the touchstone on the gold material, it will cause golden streaks to come off. When you pour acid onto the golden streaks, the reaction will determine the karat or the authenticity of the piece of gold.

As new gold testing kits come out, the technology used for evaluating gold and silver also become more advanced. The use of ultrasound is one of the most recent technologies to come out in the industry. It uses ultrasonic detection technology to calculate the density and distance that the sound travels by solid gold. Different types of metals have varying sound velocity and density. Hence, the accuracy of the test makes it a reliable way to determine the authenticity of gold or silver. It is also the preferred method of testing in this modern day and age because of the convenience and ease of use. Even if you have no prior experience to testing gold, you will be able to operate the system with ease.

Make your investment count! Stop being tricked into buying fake gold at the price of genuine gold pieces. Learn how to test silver bullion and gold materials using the GT-Ultra testing system. This testing kit utilizes the power of ultrasound to check the authenticity of gold and silver. Hence, you will never be scammed again.
