Spectacular color burst (and the bottom's not bad either) - larger than a palm piece - stands very nicely too.
Very solid piece - this is rather blocky - and the color on top is just a bit lighter (though no less interesting) in person. The matt bottom has great color too, as you can see from Photo B.
This type of material is rare, especially so big, and naturally standing! It's not entirely snow white, with some reddish residue on it, but it's quite a showpiece.
