Some Venetian millefiori beads are highly desirable and will fetch respectable sums at auction. Many others are just ordinary and plentiful and won't attract much interest. Condition is very important. The whims of collectors can be difficult to predict. Certain colors and canes are less common than others. As Rosanna mentioned, rounds, ovals and tabs are worth more than cylinders.

The prices are down from a few years ago, but the beads still sell and are popular with certain buyers.
