Category: Jewelry and Gems Jewelry and gems are two of the most popular categories in the world. From diamonds to moissanites, sapphires, and more, people love collecting and wearing these beautiful stones. However, not all jewelry and gems are created equal. That's where diamond testers come in handy. Diamond testers are tools that allow you to determine the authenticity of a diamond or other gemstone. They work by using light waves to measure the refractive index of the stone, which is then compared to known values for different types of gems. This allows you to quickly and accurately identify whether a stone is real or not. There are many different types of diamond testers available on the market, ranging from basic models that can only test diamonds to more advanced tools that can also detect other gemstones like moissanites and sapphires. Some testers even include additional features like a loupe for magnification or LED lighting to help you see the stone more clearly. In this review, we'll take a closer look at some of the best diamond testers available on the market today. We'll examine their features, pricing, and performance to help you make an informed decision about which one is right for your needs.
