GEMS 10X 18mm Triplet Loupe-Chrome

GEMS 10X 18mm Triplet Loupes with chrome cased are made in Taiwan, not China or India like most other jewelers loupes on the market. All GEMS Triplets have riveted cases instead of the screws that hold together most other loupes. GEMS riveted cases keep their tension indefinitely while screws can come loose, get floppy and finally fall out over time. If you ever owned a floppy loupe you know how annoying that can be! 

The lenses are made in Japan using the highest quality optical glass. The lenses are also protected with a special treatment making them anti-reflective and scratch resistant.

The triplet lens itself is corrected for spherical and chromatic aberrations. That means that they have minimal distortion around the edges (spherical), and are corrected for color distortion (chromatic) which is also present around the edges in uncorrected loupes.

GEMS 10X 18mm Triplet Loupes include a soft storage pouch and 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.
