Frederick, the "Edo glass" beads are graduated in size and only those in the center of the necklace are 1/4-1/3 inch in size.

Please explain your comment that size matters in light of the graduated size of the "Edo glass" beads from small to large? Does only the size of the largest beads matter? If I posted an image of the small beads near the clasp and listed their small dimensions, would this information would have been misleading? Were later beads graduated and early ones not? Were later Edo beads (not "Edo glass" beads) graduated and shiny (eBay item number 272595365222, mentioned above) and early ones not? Just trying to understand your comment that it mattered to post the size.
