Ok, I went looking again for examples of the large elongated ovals I like to call 'torpedos'.

I enlarged the image to screenshot a few beads and realized there is a breciated star in the center of the canes on one bead. Cool. Mostly I wanted to show the shape is on these bead cards from the early 20th century.

All the components for your beads are known to be Venetian. Not all variations and examples are photographed or documented in one place.

Sorry your buyer didn't like them.
