My little collection of green "Russians," peridot on the left, emerald in the center, brand-new-looking on the right.
The little teal bead second from the top of the short strand has an opaque or translucent green opal core.
The last bead on the short strand is different from the bead above it, although they look similar. The 7 sides, faceting, hole, and ends of the lower bead matches the strand on the right, only it's smaller in diameter. The upper bead was cut from rounded cane, has a slightly more yellowish tint to the green.
Beads on right vary under 9x9mm.
The comparatively pristine condition of the right strand of beads made me wonder if they were Henry Merle products (Mexico, c1980s according to the Picard Exhibit). Or perhaps they are the Czech Ornela 7-sided versions that were produced in the 1990s (of which I still have bags full of blue and red in their original Jablonex plastic packaging, but no green). The ends in particular look polished somehow, not a feature encountered on the old Czech beads, altho the Ornela beads show it. However, they're bigger than than the approximately 7mm Ornela beads, with the exception of that one bead at the end of the short strand.
Placing my money on Ornela...
OK, that's today's adventure in obsessive compulsive nit-picking.

How did you soften the shadows on the right photo? I can see you didn't move them, everything is exactly the same except the lighting.
Nice collection.
Found another strand lurking in an old box, so I combined the beads with the dark topaz and purple beads from the previous sort.
These look black or deep brown until you hold them up to the light.
