Anyone polish tabulate coral?

I recently got back from a week long hunt in Kentucky.  I have tons of fossils awaiting prep.  While I was there, we found and collected a large amount of Ordovician tabulate coral.  Some of it looks recrystallized or geodized, and i was wondering if this could be cleaned and polished?  Never messed with anything like this, so any direction would be helpful.

Do You know what the replacement mineral is?

I'm not sure.  They are pretty though.  I'll take some pics after work.

10-4, I bought a kit awhile back and haven't been able to use it yet!

Ok, so I've tested it, and its quartz.  I've taken a few quick pics, I have much better pieces outside, but this is what I'm working with.  My pieces range in size from baseball to bowling ball and larger.  Can this be made purty?!

It should be good to polish or make cabochons with.

If You have a rock/tile saw to get a flat side and a flat lap to polish it, or a cabbing machine.

It does look like the piece posted is not solid and this can detract in a cabichone.

I have a rock saw, so that's no problem. Some of the larger pieces are solid, so I don't think that's a problem either.  But I don't know what you mean by a flat lap?  Are there any online resources that may provide instructions?

A "flat lap" is a grinding unit that has a flat disk for grinding and polishing a flat surface, as opposed to the typical round grinding wheels for making cabochons.

You should be able to find a lot of information on "flat lap" by google.

Wow, those things are a little more pricier than I would expect.  I wonder if I can just attach polishing wheels to my wet saw?  Maybe I'll make one...dunno, but the polishing may have to wait a bit, especially with my Kentucky and Iceland trips back to back :(
