Big center drilled keishi pearls have fairly wide profiles for a bold appearance. Nice bright white color & very good luster with a bit of opalescence. Note from the picture that some strands have very uniform shaped (strands in the center) and some have some more cupped or elongated shapes (strands towards the outer part of the picture). Pearl sizes average about 9.5mm, but you will see some as small as 8.5mm and some longer ones up to 11.5mm. Sold by the 15.5 inch long strand.
