I have a few pieces of Burmese Amber such as this one. The surface is not as translucent as others. It looks like it could do with a further polish. How do I go about doing that?

just dug this up, tried to buff it with some wool and oxide polish but it just scuffed it up instead. I guess there was limestone in the fossil and now it looks chalky. any way to make it look good again or is it ruined.

While vacationing in northern Minnesota, I picked up this piece of Mary Ellen Jasper. My goal was to have one side polished in order to bring out the features of the stromatolite. Unfortunately, my attempts to find someone locally to polish it failed. Does anyone have knowledge of someone who could tackle this for me?

Have 2 pieces of pyritized wood (maybe marcasite) from the coal areas of central Illinois-Farmington. One is a slab and the other a branch. Have included photos. I believe the branch may have been coated with clear lacquer. The slab has not been coated but it is deteriorating on the surface. I had some pyritized snails from the same area from 40 years ago. I had lost them for many years and recently found them and they had disintegrated. Would ike to poish if possible and stabilize the finish. Would appreciate any guidance. Thanks Gerry

I've never put much time into sectioned and polished fossils, usually just because I don't usually collect material that would look well cut over whole. While preparing a trilobite I collected in Illinois over the Summer and I was cutting sections off the matrix bottom so the matrix lay flat as a stand. To my surprise I ended up cutting thin sections through a Favosites coral that piqued my interest. Coincidentally, this was at the same time @FranzBernhard posted his thread demonstrating a low-cost approach to polishing and sectioning small carbonate rocks and fossils by hand. With such a handy guide put forward at a perfect time I decided to try my hand at sectioning and polishing fossils. I was waiting on grit polish in the mail for a while and that has now arrived which allowed me to finally try some sections myself. I figured I'd post the humble results here so as to encourage more people who might be interested in trying this. I've cut lots of rocks before but this was my first time attempting polishes. The uneven cuts from some of the specimens are noticeable in the polish. I tried to grind some of the surfaces even before polishing but this was more difficult for the hard material. Oh well. I think I can improve the fine polish on a lot of these by putting more time into them but I think this was good as a first attempt.

I’ve been collecting for a year now. I started to make a limestone sink, because I love the limestone that I find marine fossils in locally. Well part of the process was polishing the bowl I cut out, and wow, polished black limestone is a thing of beauty. It even has some fossils in it. I’ll post the sink one day. Naturally, I wanted to try polishing a fossil focus piece. I found this nice coral, likely Rugosa. I polished it to 3,000 grit with a Dewalt polisher and a set of stone polish pads. It was a quick experiment but I liked how it turned out.

How to polish ammolite and make it look shiny and multicolored
RiseOfTheExtinct posted a topic in Questions & Answers
I've posted some pictures of the ammonite I bought and want to polish. If you look at the third picture, (ammonite 2.jpg), you will see that on the ammonite some rainbow color resides. I want to make the whole ammonite that color. Is there any way to polish it to make the rainbow show more? Correct me if I'm wrong, but that rainbow color is fossilized mother of pearl aka Ammolite. Does anyone know the following? If you could answer, that'd be a big help. Thank you for your future words! Any suggestions welcome. You'll never know what will work. The best way to clean and polish the ammonite to make the ammolite show and without breaking the fossil. A way to preserve the color when and if I polish it. Thank you so much, everyone, for your future ideas! -
I just got this neat piece of Burmese amber in the mail. Rough piece with a sea lily star in the attached rock. It is a very large piece (66 grams), and looks neat rough as is. But I can't help wondering what it would look like with the amber portion polished, especially if there are any insects inside. Any thoughts on whether to polish it or leave it as is?

I have a rock tumbler I don't use but it is very good. I don't have much fossil hunting equipment. I really want a pick hammer. I only carry a trowel when hunting. This will also boost my fossil hunting luck.

I have some megalodon teeth that are prime candidates for being “diamond polished”. I just don’t know what tools to use. Or if I need a certain polish. I just have no idea. Also how to add graphite into the teeth to polish. I think that’s really cool too. If anyone has any advice it will be greatly appreciated. Thanks

Can anyone shed some light on how these fossils, which are often seen in either single specimens or large slabs, ..how they are polished to such a clear diplay, and then on the back side there is normally a similar fine cut, but with a very bad finish. Also, i find that these fossils are ussually all the same color, this is due to the fossilization conditions such as, materials, region, era, ect... Correct? Also peculiar that they often do not contain other traces of the organism.

I have found a number of fossiliferous paleozoic stones of various sizes, types, and quality, in a cretaceous conglomerate layer. I have included a picture of some of them. I rather like them because, although the fossils are not very high quality, it is neat to think about how they have been fossilized and eroded out multiple times. I was thinking about running them through a rock tumbler to polish them, but I am concerned that the hardness of the fossils compared to the rock might present some sort of issue. Does anyone have any thoughts on why this may or may not work?

Can I use veg. oil on sandstone fossils without damaging them?
icycatelf posted a topic in Fossil Preparation
I found a really cool Calamites fossil with exquisite detail on a wet day a couple months ago, but after a week or so of keeping it indoors, the details started to fade and the colors became dull. It springs back to life when damp, but that only lasts so long and I fear that annually applying water might eventually wear the fossil. I think I've read somewhere that you can use vegetable oil to keep rocks/fossils looking saturated, but I was wondering if that might cause any structural damage or any other ill effects to a sandstone-based fossil. Thanks! -
Just looking for a little advice on different preps
joshuajbelanger posted a topic in Fossil Preparation
Hey everyone So I'm setting up a workshop outside for fossil prep. I have tons of vertebrates and invertebrates to prep. I'm pretty experienced with preserving fossils(butvar) but I've never done any real prep work. So far, I've purchased a wet saw, stereomicroscope, rock tumbler, work bench, vice, and mini fridge(for the beer!) I have a dremel and dremel engraver, I know the engraver doesn't compare to some of the air scribes, but it was cheap, and my limestone is extremely soft. I have about 500 lbs of this limestone, and some beautiful examples(Ocala, Tampa, Bone Valley formation) fossils in the matrix. These fossils range in calcite, aragonite, and Calcium Carbonate. Any tips are purchases I should make would be welcome. Particularly polishing and bringing out color. Thanks in advance. -J- 6 replies

I recently received a piece of dinosaur bone that was cut with a saw and nothing more. I'd like to be able to the patterns in the bone without having to look through the saw marks by running it under water. How would I polish it without messing it up too badly? Sandpaper? The bone is supposedly from the Morrison Formation.
