I have a similar strand and feel that these are post-war Czech beads for several reasons including the fact that the design is entirely applied onto the bead. My beads are purple, which is more of a post-war color too. My necklace appears to have the original clasp and bead caps. The clasp is a fish hook into a 60's looking box. My genuinely old Venetians in this style have the flower directly on the surface of the bead, it is not raised. I attached pictures of the strand with other Czech beads and with early Venetian beads.
