| I have never seen such inclusions in a Mount Ida quartz, the well crystallized dolomite inside of the perfect clear quartz looks terrific - wonderful specimen!

Thanks Tobi! I had that same thought when I saw the piece. To top it off it is from the collection of John S. White.

Great specimens as usual. I agree with Don, that Yaogangxian fluorite is really beautiful, I love the zoning of the crystals.
And that amethyst from Montana ... marvellous!!!
