Except for my carvings I have pretty much been all mouth on this forum. I am back to making cabs (winter sucks) so I thought I would post some pics so you can pick them apart. I do all my polishing on diamond pads that are mainly used for polishing granite counter tops. I am not using that as an excuse but I can only go to 3000 grit. The way my eyes are I can not see any difference past 1500 anyway so you be the judge. I do not have a small tripod yet so I had a (I'll say bad since this is a nice forum) time getting good photos. The depth of field is very short so part of the stone is out of focus. This stone has the specific gravity of nephrite but may be a mix? ? This one is attracted to a magnet so it must be hematite but the red and yellow to me is just pretty stuff. Any help there would be appreciated. The hematite is layered with the yellow pretty stuff then brecciated and filled with the red pretty stuff. Nothing less than a geological miracle. I love this material. I think it is jasper but I am not sure. I have found a number of pieces of this and some of it also has a lot of red with it the same as the hematite. Everything that I post, other than the carving stone, is local stone found within a 16 mile radius of Greybull Wyoming (population 1815) and the majority is found within 7 miles. For this reason this is a great place to live in the summertime. Does anyone know where I can park my baby house real cheap in Arizona or New Mexico for the winter? lol Thank you for any comments good or bad. I only learn from destructive criticism. Jim

More likely magnetite. Hematite is non-magnetic except the stuff they make in China. You are doing good. If you are using Velcro diamond discs you can buy felt polish discs and discs to 13,000 for the BD wet polisher. The felt discs are cheap. The other discs are pretty high but made for hard rock. I use 14K diamond on a felt pad after going through 10,000 discs. Petrified wood looks wet when done.

Hi JJ Thanks for the advice. I definitely use the velcro discs. I run 10 to 15 stones at a time but with the velcro it is easy to run one all the way through. I use 50 or 60 grit to grind and go through them pretty fast. I just ordered new 60 and 120 discs that cost me $30 each so I am hoping they will last longer. I had been buying them for $7 before. The felt discs sound like a great way to go. Do you sell them? I started with four inch but I am switching to five inch as the fours wear out and wish that I would have gone with the seven but did not find them until recently. I would like to try 500 grit with a felt pad to see if it would smooth out the fine ridges also. Jim

Jim, your cabs look real good! I love the color of the ?nephrite? The others are really nice too. It's good being able to find cabbable material right "out the door".

I like the nephrite too. Really pleasant shade of green. The banded yellow and red with hematite may be the material trade named Mugglestone ( also maybe sunset jasper) Rockyraccoon ( Kim) traded me some that looked just like that that she imported form South Africa. Similar geology in your area may have produced a similar stone. Really rough to saw on my old saw. Haven't tried it on the new one.....Mel

Thanks all Mel, All of the pieces that I have found are of trim saw size except for one and I could probably only get a couple of slabs off of it is the slab saw. IM your address and I will send a small piece so you can compare they. Jim

Yea, those are great! All that really matters is that you like them, but, as you know, when other folks like them tto, that is icing on the cake. I think you done good on them, nice shine!!

I also use the velcro resin pads up to three thousand grit and then go on to felt for the final polish, the red and yellow stone looks like jaspilite from a Banded Iron formation a similar stone can be found down here on Mount Brockman station.
I also use a pre polish resin pad on some stones, not certain what size grit (even the supplier doesn't know, they simply call it a buffing pad) but I guess that its around 15000, it does what it says on the tin.
Take care.

A little late to the party, but the green looks like epidote to me, the local geologist turned me on to is and I cut a nice little cab the other day, didn't polish yet though, but all yours looks sweet. Love that blue and tan Jasper stuff. Is that from the blue forest?

Bushkraft beat me to it: it does look like what some call jaspilite around here, a cousin of banded iron formation (although BIF frequently looks more sedimentary with true layers).
We have lots of it in Minnesota, but most of it does not have the yellow.

Bit late to jump in, but the cabs look interesting and good enough to take bite out of them.
