What Is a Magnifier
Jewellery professionals use a magnifier, also called a loupe (pronounced loop), to inspect gemstones and other jewellery. These magnifiers have special lenses that allow our eyes to focus on an object at a much closer distance than is normally possible, making the object appear to be larger and revealing tiny details we couldn't see with our normal vision.

One Lens or Three?
Loupes are labelled 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 Jewellery
A 10X triplet loupe is a good choice for viewing jewellery. 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 colour of the object you are viewing.

One Lens or Three?
- One: Loupes made with a single lens are generally of poor quality; distorting the object you're magnifying and adding flashes of colour to it.
- Three: A triplet loupe is a magnifier that contains three lenses placed together in such a way that distortion and colour problems are corrected.
