These look like an unusual shade of blue on my monitor, sort of grayed, very lovely.

These appear to have five layers. However, the cane has two sets of submerged white stripes. That means each strip round is covered by a thin layer of the external bluish glass—providing two extra layers for a total of seven.
Gooseberry beads also have submerged external stripes, but only one round, and the glass (as mentioned in a reply already) is colorless/clear, sometimes tending toward greenish or yellowish. ALSO, the true early "gooseberry" beads were made (finished) by the a speo method—though later editions were/are not. The latter are either straight cylinders (cane pieces with trimmed ends, possibly slightly tumbled) or they are hot-tumbled (like big seedbeads). The late versions also have superficial stripes. These characteristics serve to distinguish one group from the other. Nevertheless, the late beads are often sold as the early specimens (online and elsewise).
I would not call the present beads "blue gooseberries" or the like. I showed them in my article on rosetta beads (Part IV) in 1983/84.
