It is marked on the clasp: SILVER CHINA NO23...a mark similar to the mark on the Qilin bracelet but without the initials...which suggests that #23 is the name of the workshop.
The symbols remain uniquely Chinese. Guan Yin is at the center and on either side of her is a figure holding a pair of fish, symbolizing abundance and harmony. The charm below the Guan Yin is a pomegranate, a symbol of fertility because it is full of seeds...another popular wedding gift ...so we can assume this necklace was a marriage gift for a bride.
Guan Yin is only one of the many names and spellings for the feminine goddess of mercy revered throughout China and other Asian countries for thousands of years... she does not usually appear in any of the export jewelry made for the west... it is nice to see here that she has made the transition to the 20th century!
