GEMS 10X 22 mm Hexagon Triplet Loupes are simply the best value in premium diamond loupes you can find. This is the silver* with black rubber grip version of the GEMS 10X Hexagon Triplet Loupe. The GEMS Hexagon Triplet Loupes use the same Japanese made lenses that are found in the most expensive jewelers loupes in the world. Why pay more?
With a GEMS Hexagon loupe you get a the widest possible lens, at 22 mm diameter, so you get the widest possible field of view. The lens is achromatic, that means it is corrected for spherical and chromatic aberrations so diamonds and other stones viewed have minimal distortion around the edges (spherical), and are corrected for color distortion (chromatic) which is also present around the edges in uncorrected loupes. Made in Japan using the highest quality optical glass, these lenses are also protected with a special treatment making them anti-reflective and scratch resistant.
All GEMS Hexagon Triplets are assembled in Taiwan using Japanese 22mm Triplet optics. They are professionally packaged with a soft storage pouch and each one includes a nylon lanyard.
10X Triplets are used to color grade and clarity grade diamonds. For clarity grading, if the flaw isn't visible with 10X magnification, it does not exist for clarity grading purposes. Higher power loupes are difficult to use as they have minuscule fields of focus making them rarely used in gemology applications.
*The silver color is best described as a non-reflective aluminum anodized look.
