If you can fill the cracks, it would make some beautiful cabochons- I live the color in that material.  I recently invested in some Hot Stuff and Super T to experiment with from http://www.caglue.com/CA-Glue_c_10.html.  Most lapidary enthusiasts recommend this for use and Hextal takes such a long time to cure.

Thanks for the suggestion, Gina.  One of my concerns with using a CA glue on something this fractured is the quick set time.    It would work well for gluing two pieces together, but I don't see how it would penetrate sufficiently into a variety of cracks before setting.  It would be lovely to have something like the Wood Hardener in the video - put a rock in, apply vacuum, and let the glue replace the air.  It sounds like you might be able to use Hxtal like that from what little I've read about it.  What do you think?

Super glue works fine . It is standard for lapidary items and there is even an accelerator  specifically for rocks. A warm rock helps but glue wait a minute and accelerate and cut. Using it  after the piece is preformed and rough ground is best if the quality of the rough allows.
