At least until some cool idea pops up in your head ;)

Unless you went for a monster suite I'd probably keep it whole.

Uhmm... I don't own a cabinet here. :lol:

My best idea so far would be to make a series of round cabochons, exactly of the same size, showing the different colors. Like those cool gemstone suites* showing e.g. the colors in garnets, sphalerites (I saw some pretty ones in person, from gemfrance at the Mineral Show in Lyon last year), etc... The resulting series would be a nice display collection, or a matched series for a neat necklace, I guess. I should ask the females around about this... I'm not really into fashion jewelry. :lol:

But still, it's a nice slab to display as it is (once polished) #-o

*I will do something like that for faceted quartz sooner or later. I need to choose the proper design, and the right size. I think it's about time to start this project.

A little bump here. Our friend who does cabochon cutting for us just came by today, and he brought these with. I thought that they were interesting enough to go here.

These are cross-sections of agatized crinoid stems, something I haven't really seen before. However, we The color, lustre and overall look turned out much better than I had expected, a bit of a lavender hue to it. I think they should make some very beautiful earrings.
Image
This one is a slice of a fossilized pine cone from Patagonia. Nice, very finely banded chalcedony has replaced the seeds and fills small pits throughout the stone. Very neat material.
Image
This is a length-wise split of a crinoid stem, in one of the neatest arrangements of a fossil in matrix I have ever seen. I really liked how the composition worked out in the cabochon as well.
