Venetian beads with aventurine decoration are more rare than those without - but I guess it's one of those corners of bead collecting that is up to the collector as to how valuable and/or desirable they are.
There is a nice chapter on the history of aventurine glass (aka goldstone) in the The Glory of Beads - see details on the Classified page.
