Summary 30X21 The 'standard' magnification for a loupe (for jewellery & gemstones, stamps & coins) is 10X. This one is 30X The diameter of the lens is 21mm Useable diameter of this lens (allowing for the rim that holds the lens in place) 18mm. Too see reviews of loupes, click here Detail This really is the largest possible strongest possible loupe with the highest quality triplet lens (even allowing for the "useable" area of the lens). However, there really are limits as to what can be done technically - the image is crystal sharp in the very centre, most of it is very wobbly. This said, if you want the largest possible strongest possible loupe with the highest quality triplet lens - this is the one.   Further information Everything you need to know about magnifiers and magnification. See information about (and reviews of) loupes (small high-power folding jewellers' magnifiers). See information about (and reviews of) binocular (head-worn) magnifiers- especially the surgeons-type.
