What are jewelry loupes?
A jewelry loupe is a precision instrument that consists of a small magnifying glass with two or more lenses used by a variety of people from rock collectors to weapon smiths.
As the name suggests jewelers use them the most.
The loupe has several advantages over a traditional, Sherlock Holmes style magnifying glass, also called a singlet. The traditional magnifying glass magnifies different colors differently so different colors can be slightly different sized.
The loupe has a second lens, called a doublet, which makes them achromatic.

They correct most of the chromatic aberrations that distort the image. In addition, the surfaces of the lenses are aplanatic meaning they aren’t perfectly round or flat, but complexly contoured.
This keeps the edge of the image from becoming blurry, which occurs on a single lens magnifying lens. The trade-off is the viewable area is smaller on a jeweler’s loupe than a regular, single lensed magnifying glass.

Why would anyone need such a powerful tool?
Scientists, numismatic coin collectors, diamond appraisers, and micro-engineers all need the level of detail provided by the loupe. Imagine you are a jeweler.
You want to assess the clarity, color, and cut of the diamond. With your naked eye you can see the color.
What about the details of the cut or any blemishes? For that you want something that is much stronger than your eye. Any coin collector, jewelry appraiser, or rock cataloger should have one.
Loupe users say that they need to be able to see enhanced views of images with clear details. With that in mind, the aspect of the loupe that was the most important overall to customers was the quality of the lens.
While not universal, customers of higher quality lenses were often unwilling to consider lower quality lenses with many saying that they gladly bought the more expensive loupe over lower priced competitors.
