That is simply spell-binding. I could stare at it a very long time... Thanks!
I don't recall seeing it before.

Very nice material! I have looked at an awful lot of granite, have found very, very little good graphic granite. It is an intriguing rock.

Here's a few pics of some graphic granite we picked up at the Blue Lady Mine, mentioned previously in this thread. It is in a pegmatite area.
Couple 'o chunks 
A few slabs 
Cut with the grain. Across the grain is better, just wanted to see what it would look like. 
Don't quote me on this, but my understanding (from 1dave) is that as it is forming in the pegmatite, the slower it cools, the larger the quartz crystals. The quicker it cools, the smaller the crystals. There was also tourmaline in that mine, hence the dark blue/black areas. 
And this is a cab I made of a piece. I gave this cab to snowmom Deb a few years back. 
Hope I didn't bore you too much! |

There are 2,000lb boulders of this stuff just east of the rocky mountain front. A lot is quite weathered and unusable, but I'm sure the centers would be just fine for lapidary use Perhaps I need a bigger saw. Lol Colors vary from salmon to bright orange, reds, greens, whites, and classic almost solid pink with quartz trailers. Every one is very different. Some have tight, small quartz patterns, others very large blocks. Interesting about the cooling, thanks 1dave |

I love that cab Jean. I had no idea this stuff had so many Sources.

Thanks, Randy. It's pretty common out here. Not surprising, since our mountains are made of huge batholiths of granite, in various stages of weathering down.
