The blue beads vary around 30-32x12-15mm.

The amber glass beads vary around 30-31x12-23mm, have small holes and narrow flattened ends, and seem to match closely those in Strand 6, page 16 of the Picards' book on "Russian" beads, described thus:

"11- and 12-sided with a total ot 55 or 60 facets; translucent light amber.These beads were molded, not drawn."

Karlis Karklin's book indicates the measurement of the sort of bicone dark cbalt bead on the Levin card to be 27.3x12.8mm.
