Yes, there is a similarity to the weight in the Evelyn Campbell Cloak book. Both use "heavy-looking" goldstone (aventurine) threads as well as coloured threads with aventurine edging. The attribution stated in the book says it was acquired in 1939 and is "possibly mid-19th century".
The same weight was illustrated in the later book Glass Paperweights of the Bergstrom-Mahler Museum
(item 235). The description was much the same as in the earlier book but with an addtonal comment referencing Hollister Jr, The Encyclopedia of Glass Paperweights
where a cross reference back to weight in the Museum is accompanied by a statement about its possible 19th century Venetian origin:
If it is, it is the finest Venetian weight ever made ...
The statement goes on to comment on the filigree used and makes a reference to the "Venetian balls" of even earlier times.
The problem is that 19th century Venetian weights (or "balls") were usually of the "surface decorated" millefiori types by Bigaglia (maybe also Franchini?). Later 19th century items tended to be mixed coloured twists with aventurine, also with surface decoration under a thin outer coating of clear, but of a more flattened profile.
