A jewelry loupe is a small magnifying glass used by jewelers and gemologists to closely examine gemstones and jewelry. Typically, it has a magnification power ranging from 10x to 30x, allowing users to see fine details, such as inclusions, cuts, and overall quality. Loupes are essential tools for assessing the value and authenticity of precious items. These devices are often compact and portable, making them easy to carry in a pocket or tool kit. Many loupes come with built-in LED lights to enhance visibility in low-light conditions. They are widely used in the jewelry industry, as well as by collectors and hobbyists interested in gemology.
