Thanks for the refresher, and the newest chapter on the 10lb mix. I have but a few examples. And from back in the days that I worked for General Bead SF, they had a few marquis-shaped small point-backed "stones". They were part of a large job-lot of vintage stones, where we'd glue a sample on the end of the bin-box...when the items were sold out, the box would be discarded...and even though I didn't know what this glass was called at the time, I fished the box out of the trash and pulled off the 2 little saphiret stones......which are somewhere in my bead pile.
