Pale Peach Off Round Freshwater Pearls have excellent high luster, pearls have good nacre, are well matched for quality, and these Large Hole Freshwater Pearls are an excellent value for an average size off round shape. Large Hole pearls have a 2.5mm inside diameter produced with a 5 step drill process to insure a cleanly drilled hole without abrasion to the nacre and to allow a consistent diameter through the pearl.
