Very small, smaller than a dime for sure, a little bigger than seed beads but I have difficulty in gauging size in beads so that's all on me, I was expect them to be cold to the touch and have some weight but not a negative experience I will include them with other beads any way. Tag says natural turquoise and they may be but I collect crystals and have worked in a geology museum, I guess I'm just not familiar with turquoise that well, guess I should study up lol! Thank you though for such beautiful coloring.
