The reference standard in jeweler's loupes Oct 21, 2008
By New England Yankee Bausch & Lomb loupes are used by jewelers everywhere. The 10x is the most useful for diamond evaluation, and a triplet like this yields the best view in terms of distortion and color accuracy at a reasonable price. They also make the Hastings Triplet in 7x, 14x, and 20x.
It is handy to have a multiple around too (loupes that have multiple lenses that can be used either individually or together), but useful as these are for examining a variety of objects, they should not be relied upon for critical examination of of gems.
A loupe of this quality can be used with some precision by an expert. Even so, it is still used mostly as a quick grading tool and for in-store use. Fine grading and certified grading is done with a microscope and other tools. I take my Bausch & Lomb triplet along anytime I go near a jeweler or an auction involving jewelry!
Another reviewer who unfortunately got a bad Bausch & Lomb loupe mentions the Belomo loupes from the Eastern Bloc. Some very good optics are coming out of the East and these are good too. I would take issue with the comment over size, however. 10x loupes are used very close to the eye. You really don't need a loupe larger than the Bausch & Lomb, larger lenses introduce their own usage issues, and, of course, a small loupe is easiest to keep at hand. He also mentions the Bausch & Lomb plastic lens cell. That's a complete non-issue. There are telescope, binocular, and camera lenses with plastic cells that cost many thousands of dollars. The simple fact is that plastic is more stable and does not stress the lens as much as metal as the temperature changes. Belomo optics are quite good. The quality of their cells and cases isn't up to the same standard.

The standard by which all others are compared. Dec 22, 2006
By R. Knapp If you want a hand lens for serious reasons, buy one of these. If you need to know why, buy a cheap one also and compare the two. Triplet lenses give cleaner images with less distortion and chromatic abberation.
10X is the best power for general use, giving a bright and clear image.

Tack sharp, color correct, but really really tiny. Jan 18, 2008
By Joshua G. Feldman
"Technophile"
I bought this for coins and gems. There are times when 3x-6x doesn't cut it and you really need a close view. Bausch & Lomb's Hastings Triplets are famous for sharpness and freedom from chromatic aberration and this one delivers. Images are tack sharp across the field of view and the colors are spot on. 14x is the gateway to world of the really tiny. 10x isn't quite close enough to really evaluate surfaces. 20x is so close it can be tough to get enough light and landmarks to know where you are. 14x is a good compromise for me - I can see where I am, but in tight enough to get a good fix on the details. The only fly in the ointment is that 12.5mm lens diameter. It's TINY! Eye relief is forgiving, but field of view becomes unacceptably small unless you get eye right up there (I use with glasses with no problem - but be aware of the need to get the eye as close as you can to get better field of view). I wish it were a little bit bigger.

Good pocket magnifies Sep 09, 2006
By Douglas L. Terry
"Doug Terry"
I've carried a 7X and 14X on a little bead chain in my pocket for years for use in the laboratory and personal use. The lenses are well protected by the nickle plated case and the view is sharp and bright out to the edges. I primarily use the 7X because it is brighter and has a longer focal length but I do frequently use the 14X for detailed viewing. These are high quality instruments and are well worth the money. You can buy plastic magnifiers with cheap lenses for a lot less money but you won't have the durability and sharpness of image that you do with these high quality magnifiers. Even if you don't need something like this in your work, they open up a facinating world such as the details of flowers and insects that you'll never see with the naked eye, especially when your naked eye is 58 years old.

Review Sep 21, 2010
By Susan W. Sprague A beautiful little hand lens - when I saw the little modified petals under the hood of a monk's hood, a brand new world opened! If you want to see little flower parts, this is a great tool.
Shipping was very overpriced so opt for cheaper options.
