Old trade beads such as these originated in Venice, Italy where they were produced and sent to Africa for trade purposes. Each bead was crafted by an artisan by applying the molten white glass dots to the black base of the bead.
The wound beads with lamp worked white spots, and some red/teal spots were made in the mid 1800's.
Each bead has about a ½" diameter (12mm)
Some call them Crows eye beads.
