I estimated 20 slabs. The thicknesses vary. They were all hand pushed through the little saw.
I could trade if anyone is interested. They’re not Linde so the QC isn’t perfect. They should all star though. The asterism is strong enough that relatively flat cabs still star nicely. I paid $2.00 per gram. After sawing and grinding off high spots, I value them at $2.00 per carat, negotiable. It seems like a pretty big jump in cost but hardness 9 and breaking during sawing makes it seem fair to me.
That little chunk with the seed crystal is pretty cool and should star. I did my best to cut them perpendicular to the C-axis. It’s not so easy pushing them through the saw by hand.
They’re all solid with no cracks. There are some saw marks that look like cracks, but a little grinding will fix them. The broken piece will make a nice star too. You can saw any of these into four pieces and get four nice stars. gemfeller these are from the source you sent me. My photography skills are less than stellar. The slabs are decent and I think all of them are cut less than 15 degrees from perpendicular to the C-axis.
