Description:

Jewelers typically use a monocular, handheld loupe in order to magnify gemstones and other jewelry that they wish to inspect. A 10x magnification is good to use for inspecting jewelry and hallmarks and is the Gemological Institute of America's standard for grading diamond clarity. Stones will sometimes be inspected at higher magnifications than 10x, although the depth of field, which is the area in focus, becomes too small to be instructive. The accepted standard for grading diamonds is therefore that inclusions and blemishes visible at 10x impact the clarity grade. Our 30x jeweler loupe magnification glass has a durable metal construction with a 21mm optical lens. It is great for rock collectors, coin collectors, jewelers, hobbyists, and also a great gift for the kids to explore the fabulous tiny world. Foldable design makes it convenient to carry around and use it everywhere you go.
