Murano glass paperweights

Some Murano glass paperweights from my collection..
1. Scrambled weights with latticino & colour twists, large size, 1950s era.
2. Two smaller scrambled weights. Left one possibly by AVEM. 1950s era.
3. Mixture of older & more recent millefiori weights. Three at the back most likely 1950s - 1960s era. Lower left & middle, both recent, probably 1990s era, op shop finds. Bottom right, 1970s era featuring opaque Moretti canes more often seen in beads.
4. Two interesting weights that feature short segments of cane that resemble a type of bead well - known to trade bead collectors as "white heart beads", due to the opaline core. One miniature & one large egg shape. The "egg" does not fit in my glass - topped coffee table, but now serves well as a bookend. Uncertain of the age of these, but I will guess at early to mid 20th century.
