Malachite, Chrysocolla, Agate and Romanechite

Beautiful piece, but the cracks will make it a pain to try and slab and cab. Perhaps it can be stabilized, though chrysocolla can still be friable even after such treatment. So maybe just a specimen piece, like for a cabinet display, would be best?

If I may make a suggestion: Next time, put something in the picture to show the size of the specimen. Lots of people here on DA are visually focused, and they need to see a comparison to get a sense of size. Just writing the size in text doesn't always do it for them. I sell small glass beads here on DA, and I've found that putting a coin or a measurement next to the item has helped my sales.
