Generally speaking, the magnifying glass with magnification of 10 is the most commonly used, because it can clearly observe the details and surface features of jewelry without too strong distortion. In addition, some skills are needed when using 10 times magnifying glass to ensure the accuracy and reliability of the observation results.
In addition to 10 magnifier, there are other types of magnifiers to choose from, such as 20 times, 30 times or even higher magnification. These magnifying glasses can show the microscopic features of jewelry more clearly, but they need more stable hands and more skilled skills to use.
