snakebite6769 Posted December 3, 2012 Share Posted December 3, 2012 I found this today, while walking the sugar run formation in Illinois. The pattern threw me for a loop so I had to grab it and ask if anyone could help identify it, maybe its just a hexagonal rock from nature, maybe not. I hope not.

dragonsfly Posted December 3, 2012 Share Posted December 3, 2012 Take a file to it or give it a vinegar bath to see if its gemmy inside. Link to comment Share on other sites More sharing options...
ghost1066 Posted December 3, 2012 Share Posted December 3, 2012 Ruby and sapphire both have that shape. Not sure if they are found in your area but they are east of me in the mountains. I worked in a rock shop and had some that weighed over 1000 carats. Or it could be a chunk of quartz crystal. Clean it up or cut it with a lap saw to find out.

CH4ShotCaller Posted December 3, 2012 Share Posted December 3, 2012 Here's an example of a sapphire from western North Carolina, it has that hexagonal shape.

I clicked on the picture without reading thinking Snakebite posted a picture after cleaned-up ... Looks like a twin !!!

CH4ShotCaller Posted December 3, 2012 Share Posted December 3, 2012 WOW ... I clicked on the picture without reading thinking Snakebite posted a picture after cleaned-up ... Looks like a twin !!! LOL! I was going for that effect! I forgot to mention, corundum is also much heavier, you'll know if you got one of 'em.

painshill Posted December 3, 2012 Share Posted December 3, 2012 The formation is dolomitic limestone originally deposited as calcite mud, is it not? Wouldn’t a more likely explanation be that it’s simply a hexagonal dolomite crystal which might also be a pseudomorph after calcite or aragonite? That’s what it looks like to me.

JimB88 Posted December 4, 2012 Share Posted December 4, 2012 There is no metamorphic or igneous rock in that area, so I would go with painshill on this one. Link to comment Share on other sites More sharing options...
Herb Posted December 4, 2012 Share Posted December 4, 2012 Looks like a piece of dolestone to me.Maybe a styolitic form?

Indy Posted December 5, 2012 Share Posted December 5, 2012 Whatever the mystery represents ... It sure looks like a twin of the specimen CH4ShotCaller posted (reply#4) Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
Rob Russell Posted December 5, 2012 Share Posted December 5, 2012 That's an interesting piece you've found, Rob. I see no signs of mineral, or geode here, so I'm going with just a piece of dolostone. Due to the poor preservation of the dolostone, and without any distinctive identifiable characteristics, it's almost impossible to say for sure what a lot of things are down there. Other than the shape of this piece I'm not seeing any other identifiable traits. So if it's organic in origin one may never know. Just my 2 cents. Finding my way through life; one fossil at a time.
