At Facebook, Venetian Glass Beads Group, we have multiple discussions over whether mixed-murrine millefiori beads were "made by Moretti," or merely "made (by some company) exploiting Moretti murrine." I'd offer here that the beads you show were made by Ercole Moretti, post ca. 1920.

And, by the way, actual Moretti family members participate at the Group.
