Weren't Campanella more known for the geometric sommerso vessels, in single colour (often brown, grey, or pink) then clear glass combos? I've had a a few with Campanella labels in the past, and they've always been facetted sommerso examples. Also, Campanella are a relateively recent company (ie, post 1970), and these aventurine items seem to date to the 50s or 60s (though are probably in production still, though). I dont think it's possible to put a name to them.
