I thought when I first saw this post from Degumay Sareh that this was a very early, modern era, venetian bead, possibly with Franchini canes. The image is not very clear but the colour palette and general appearance are similar to illustrations from the book Miniature di Vetro: murrine di vetro 1838-1924 by Giovanni Sarpellon. In particular there is a picture (556) of a paper weight with rosetta cane decoration which looks similar though the text states that similar paper weights have been produced in Venice since the 1400s. Possibly the first modern era tubular millefiori beads (553) are shown (8 beads) though they were probably never commercially produced.

The book talks about the revival of the art of glass making in Venice after it had almost disappeared in the early 1800's. In particular it deals with the 19th/20th century production of figurative canes depicting animals, portraits, flowers, buildings etc. The procedure for producing figurative canes develops from chevron/rosetta and latticino through concentric complex millefiori to figurative canes. Franchini produced canes made up from more than 160 simple canes.

The development of the modern millefiori bead would seem to date from no earlier than the 1830's and more probably from the 1840's.

On a slightly different but related subject, has anyone heard of "bandiera beads"? They are round or oval millefiori cane decorated beads found in Ethiopia. Each bead is decorated with a variety of different cane slices and tends to have fairly abundant base glass showing between the incompletely marvered (is that the term?) slices. I have been told that they are earlier than other millefiori beads by someone whose opinion I respect. They also look to me to be earlier.
