10x Magnification 21mm Jeweler Eye Loupe Triplet Lens with 6 Built-in LED Lights *****           This 10x Magnification Loupe is an ideal tool for Jeweler, laboratory and industrial use and is the most widely used and most familiar gem-identification instrument. It has quality triplet lens (contain three bonded single lens), achromatically and aplanatically corrected, highly corrected for spherical and chromatic aberrations and diffused & perfectly balanced 6 LED ring light on the bottom. Perfect light for viewing diamonds and other gemstones up close. We highly recommend this loupe for beginner and competition faceters, but it is also great for any job that needs 10X magnification in any brightness condition. With a 21mm aperture and optical glass lens, those who use a loupe all day long will rarely get eyestrain. Sufficient illumination plays an important role so that there is enough light to allow you to see clearest view of a magnified object. A 10X loupe has a one-inch focal distance, anything present in a stone at a distance of 1inch from the end of the loupe will be in focus. In addition, you also have latitude in terms of the area in focus, anything present at a distance of only ¾ or 1¼ of an inch, will also be seen. The loupe can help determine whether a stone is natural, synthetic, glass, or a doublet (stones that consist of two parts glued or fused together to simulate any gem desired). It can help identify characteristic inclusions, blemishes, cracks, chips, scratches, and bubbles. And at the very least, the loupe can help determine the workmanship that went into the cutting of the stone, such as symmetry, proportioning, and alignment of facet edges.
