Nice to see you here on bcn! I concur - nice beads - they come up in discussion every now and then. My first ones came from a friend who found them in a folk art gallery in San Francisco in the late 80s. Then we found some with a guy years later who seemed attached to some folklore related to the Naga re. these beads, but we concluded that this was wishful thinking of the seller's part, and done due to the long Naga shell beads of similar dimensions. Also, these usually have some pseudo-aging on them.
