This 18.5" long strand of natural color pearls weighs 32 g. The pearls were harvest in the 1970's in Lake Biwa, Japan. Now long defunct, this strand is part of a long standing family collection (Rudolf and Frida Voll, Pacific Pearls). The pearls in this strand have gorgeous luster and very well matched gentle nugget shapes. The pearls range in size from 6.3-7.5mm. This strand is unfinished. Please let us know at the time of purchase if you would like us to knot and finish these pearls into a necklace for you. ID#P9186
