This vintage horseshoe shape pin features 29 small pearls, all believed to be cultured. There is a little irregularity to the pearls, I believe a few may be replacements. They range from about 1.9mm to 2.9mm in size, some are full pearls, some are 3/4 pearls. The pin measures about 1 1/8" long , with a width of about 7/8". I believe this one could date to 1910-1930. Marked "14k" on the pin catch, the piece weighs 3.7 grams.
