1g Large size 18/0 cylindrical beads in Cobalt Blue (pre-1900s)

This is a 1g pack of vintage- opaque Cobalt Blue cylinder beads. They are pre-1900s- being made over 110 years ago in Venice. The beads in the top of the photo are Miyuki size 15/0 lava red seed beads so you can compare the size with modern beads. Although they came from an unopened box labelled 18/0 there are a mix of bead sizes and some appear to be closer to a 15/0 or 16/0 in size.
