My first thought was 19th C Murano, or at least someone trying to imitate it. I don't have a problem with the handles, and, while I can't say I like the colour combination, it seems appropriate for the period. See, for example, Item 132 on p.156 of "The Colours of Murano in the XIX Century." What I would question is the irregular manner in which the avventurina is applied. I'd even consider Salviati as a possible maker.
