JARLINK 3 Pack Jewelers Loupe, 30X 60X 90X Illuminated Jewelers Eye Magnifier and Magnifying Glass Loop with UV Black Light and Bright LED Light for Gems, Jewelry, Diamond, Coins, Stamps

I ordered two cheap loupes a while ago and I've gotten a lot of use out of them. But I took one to work and misplaced the other, so I thought I should order more. The two smaller ones are just like the ones I already had. They are easy to use. The bigger one also works well. The 90 magnification lens is crazy but maybe not very useful. The 30 lens is nice and big and clear. Great magnification. EDIT: Okay, the big one is now one of my favorite magnifiers. The big 30x lens is just so nice to look through, and magnifies things a ton without getting to the point of microscopicness where you just can't see enough of the object to appreciate it. Been loving it for my crystal collection and even for sea monkeys if they're close to the side of the tank.

Bought to verify the IGI certificate number on a 1ct diamond. Did the job perfectly. Incredible how this works to see things so dang small. Definitely recommend!

I got these to be able to read extremely tiny markings on some jewelry findings. The magnification was more than adequate. The black light works, I used it on some known stones and they glowed with the appropriate colors. The price on these is very reasonable and I’m very pleased with them.

Well made! Don't look directly at the light!!!!! Compact enough to fit in a pocket but don't let the size fool you. It's great to magnify gems or anything you want to see close up.

The small ones are a waste of time. The lenses are too small and the metal is sharp enough to cut you but the large flat ones is great with a functional light and large lens. It alone is worth the price.
