Featuring the beads described in the Capt. Cook voyages?

Or the beads described in the Russian accounts cited above.

I don't recollect accounts of Dutch beads that could be described as sky blue and about the size of a large pea - but have I missed or forgotten something?

As far as going by mandrel release left in the holes, many of the beads in the strands I took apart are so worn that it seems possible that the holes were abraded and polished in the same manner as the ends - rotating on a thick stringing cord that accumulated abrasive dust.
