A wonderful Jewelers Loupe It is triplet 20x21 magnification. It is made of bright polished metal not the cheap plastic types. It is made with a half loop to run a lanyard through it for wearing. You could also make a beautiful necklace and wear it when out shopping for jewelry. I have used one like this for years for jewelry and coins and love it! AND BEST OF ALL FREE SHIPPING IN U.S.A. and CANADA! A GREAT GIFT ALSO! What Is a Magnifier Loupe? Jewelry professionals use a magnifier, also called a loupe (pronounced loop), to inspect gemstones and other jewelry. 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. A triplet loupe is a magnifier that contains three lenses placed together in such a way that distortion and color problems are corrected. 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 and 20x means 20 times. A 20X triplet loupe is in my opinion the best choice for viewing jewelry. To use a loupe hold is close to your eye and bring the object closer until it is clear to you. This will be very close to the loupe. After doing it a couple of times it will be like second nature. Member has an eBay Store ANUATED
