Greetings! Can someone tell me what aspeo or a speo beads are? I have some watermelon-style beads with milky white cores that I'm told are aspeo beads, but they're quite different from other beads I've seen labeled as aspeo. I've looked in books and in the BCN archive but can't find an answer - so if someone can enlighten me, I'd be grateful!

thanks,
Julianna
