New Jeweler Loupe 20 x 21mm

Magnification Power

Loupes are labeled with a number, followed by the symbol "X," which means "times." For example, a 2X loupe makes an object appear two times its actual size and a 5X loupe shows you a times-five increase.

Best Loupe for Jewelry

A 10X triplet loupe is a good choice for viewing jewelry. It is the type of loupe used by professionals to grade diamonds and other gemstones. Anything visible through a more powerful loupe, while interesting, isn't included on a grading report.

Look for a loupe with black framing around the lens, because black eliminates reflections that can alter the color of the object you are viewing.
