I get a lot of that sort of metamorphic granite here, too, the colors it comes in are incredible. Some of it sort of walks the line between granite and stuff like the above with bits of each, all gorgeous stuff Jamesp, no matter the name I love it all! Maybe the tumbler will do well on these. Looks like some of it is going to turn out fine. And some not, learning the tumble-able ones by simply tumbling them. Waiting patiently. We can cheat by tumbling 'false' granite.  |

James,after your slurry and or grits are on the final polish-do you run them for a few hours in Ivory soap or the such??
I do on my tumbles,it really brings the shine on!! Thumbs up

Usually use Dawn Michael. Always use sugar in polish in the rotary. Even the soap does not remove it all. Soaking in water for a week dissolves the sugar well. |

Thanks Bob. There was a couple of pieces of that in the granddaughters' rocks they got from the Chattahoochee and I was wondering what it was. The granite I'm accustomed to is mostly grayish in color.

The granite I'm accustomed to is mostly grayish in color. Granite close enough, but it is probably metamorphosed, so it would be gneiss I believe. Higher quartz content, smaller mica flakes, easier to tumble due to less undercutting. The pink comes from pink felspar, common here. |

jamesp, if you have a monument/tombstone maker in the area, they might be able to give you a lead as to origins of various different granites.

jamesp, if you have a monument/tombstone maker in the area, they might be able to give you a lead as to origins of various different granites. Elberton GA, makers of half the tombstones in the US: " Elberton claims the title "Granite Capital of the World," annually producing more granite products than any other city in the world." A relatively small 6 mile X 20 mile quarry. A drop in the bucket of Georgia's granite resources. There is many granite quarries here all connected by rail. Some rails paved w/fine granite with rich colors. Hard to say which quarry they came from. Some gravel is quartzite, come gneiss, some garnet and tourmaline impregnated granite. Since liability has kept us out of the quarries rail ways offer access to these fine rocks. The gneiss tumbles well. As does the quartzite. So the rural railroad tracks around here are sure productive. It is private property but rarely policed. Just don't get caught with a bag of crackhead steel, they will get you for stealing RR iron. |

Higher quartz content, smaller mica flakes, easier to tumble due to less undercutting. The pink comes from pink felspar, common here. I've seen different colored tombstones but never really thought about the colors being a marker as to their place of origin. Rockhounding reveals things outside of the hobby, too!!! Thanks for your thoughts on the rock, I'll relay it to the young geologists. Jimi, I'll start looking at the railroad beds. Seems some of that polished up nicely. Seems you need to use fine speckled/layered rock closer to gneiss so undercutting isn't a big issue. Years ago they dug up most all the tracks and beds around here...the county used the bed material to put on the dirt roads around here. Only problem was they hadn't thought about the decades (century?) of cross-tie replacement and all the discarded RAILROAD SPIKES. People started having flats with be spikes stuck in their tires...and lots of them. If you had a flat from a spike you had to go to the country treasurer's office with a receipt for the replacement tire and they would reimburse you...begrudgingly. Begrudgingly, that is, until the country treasurer herself had a railroad spike destroy one of her own tires...after that, no problem getting a check...with a smile.  |

Always stop and see what's local to the area I think some of the rock they use on the rail road is brought in from fairly distant quarries Jimi. Those quarries linked by rail. I think the pink stuff is mostly in NE Georgia. Around Elberton, tombstone capital of the world. They may have a finished tombstone waiting for you and I, so we best behave. |

Darn women walking my railroad tracks stealing all the pink granite.  here in Texas we have some pink granite but this is the only piece I can recall finding outside Enchanted Rock state park(where from ye may not taketh stones) and the Capital building steps  and this particular one I actually cut in half and sent half to RocksInNJ so you might get to see it all polished up real soon |

My QT-66 can’t keep up with the UV-10. I’m still rolling some junk rocks in the rotary, from when I started trying to get the hang of things. Can’t wait to see what all the stuff you sent looks like though. |
