first -- it is a beautiful bowl, looks to me like it came from a top maker. (Archimede Seguso was my first thought, too.)
I looked through my books, but no match.
Closest I could find is a vase in Judith Miller's "Glas des 20. Jahrhunderts" (= 20th century glass); it has silver instead of gold, and blue "dots" instead of triangles (with dark-puple outline like in yours). Unfortunately no attribution given, just "free shaped vase Murano glass, mid to end of 20th century", and a prize guide of 300-400 Euro.
The vase has a shape similar to some " Macchie Ambra Verde" pieces btw...
Sorry, so not much help from my side.
