And here's a real nice solid piece of classic old material I was taking pics for the store of and noticed this "band" of mineralization across it's backside, so now I'm going to hold on to it a bit longer and try to ID some of it. I imagine most of it is fluorite, but I haven't been able to find a good article on the minerals of Tiffany Stone yet.
And the little vugs on the front cut side are pretty interesting, too.
Any bids?  Someone should take this away from me before I start cutting into it.

Thanks, Jewels!
