Also, I've picked up a couple of decent quality children/school quality microscopes at thrift stores for about $10. These are actually handier than some professional models as you can hold a rock under and focus by moving the specimen rather than the viewing depth. They aren't good for micro fossils but more than sufficient for most fossils.

I personally rarely use a magnifying glass. Even in the field, not that useful for fossils (used a lens for mineral crystal structure). At home I use a microscope for just about everything.

If a short focal-length 10X loupe is the tool for what you have in mind, this is the one by which all others are measured.

For almost all my prepping work I use a microscope. Only for the really large specimens that I can't fit under the microscope do I use other magnification.

For looking at plant fossils, I enjoy using a magnifying lamp. The magnification is generally less than for a hand lens, but sufficient for looking at things like pinnule venation (if you look at shale under higher magnification, you start seeing sediment/grains, which is not that useful anyway.) In exchange for lowering the magnification, you get a much, much larger field of view. Ideally complemented by a hand lens (and a microscope) for the more detailed structures, but such a lamp is probably enough to take care of basic plant compression fossil inspection.

Thank you both. I guess I was looking for something handheld, but honestly had not thought about it. I do not prep fossils, just want to see them more clearly. I am at the stage of life where reading glasses are a must, but they do nothing for looking at fossil detail more clearly. As for "really good", what I mean is a good quality that will give good magnification. Does this help?

I use the cheep two lens head visor from Harbor frt, or any other place with magnifiers, Walmart, in the sewing dept. has several magnifiers.

I think the real advice you are getting here is that there are different magnifiers for each job. I have a folding 10X loop for the field. It is small and fits in my vest pocket. I also use a pair of magnifying binocular lenses used when crawling around in search of tiny things. At home I have a large magnifier on a goose neck arm for doing prep along with a stereo microscope (thanks MikeC!) And for showing stuff to friends or kids I have a nice old fashioned hand magnifier. I've been collecting for decades and all of these have been swapped out several times for something better or different when the needed.

S40-10D for an intensive illumination in the incident darkfield, enhancing contrasts of flat structured surfaces. It can be mounted on 58/66/70 mm objectives via an adapter ring or easily be combined with all brightfield ringlights using the brightfield-darkfield adapter kit.

I find one of the best magnifiers, is a good photo of the fossil in a photo program that allows you to put the photo full frame on your computer and zoom in on it and slide it around on the screen and see different sections. I use photoshop elements ( the lower cost version for photo editing has a good full screen option, It also edits photos and resizes them for posting).

You all have had great ideas and wonderful input, and I thank you. I relate completely to the comment of the eyes not getting any younger. The fossils are mostly all very large, so a microscope would probably not work for these. It looks like I have to decide what best fits my needs as all of you have and just get one. The good thing is that they are not so expensive that I can always try something else.

OK, so I decided to purchase a nice quality loupe and ordered it from an Amazon shop. I did not realize the shop was in Germany, so took a while to get it. The package arrived today and I was very excited to get it and try it out. Opened up the package and found a glass picture frame made in China shipped from Germany....UGH!!!!!

I was looking online for a really good magnifying glass. There are so many out there and wonder if anyone has suggestions?

Anyways, the best magnifying glass depends on the use. Hand held? Clamp on? Prep work? Also, some optic devices also depend on your vision.
