Extra small rice pearls are a nice shade of Peridot Green - widths run 1.7mm to 2.1mm but lengths vary quite a bit as the picture shows. Tiny rice pearls of this size category are often called seed pearls, they are so petite. The number of pearls on each 15.5 inch long strand varies quite a bit due to the difference in lengths. Note that pearls on an individual strand tend to be similar in length, though. Temporarily strung on two threads that measure 0.13mm each. Sold by the 15.5 inch strand.
