6 x 13mm Twist Bead Strands
These beads, about 26, are on 15 - 16 inch strands, temporarily strung, usually on monofilament (clear plastic fishline).
The holes are relatively small, probably less than 1mm. You won't be putting leather through them.
As with all the natural stones, color and "look" may differ from strand to strand and even from bead to bead.
Shockingly, some of the stones are dyed.
