This very pretty pin is made of carved green and white jade and silver (marked) intricate filigree work. The jade is securely held in the setting. The mark on the back is “Silver”. The pin measures 1 ½ inches long by 1 inch wide. It has a roll over or locking c type clasp that works well. Pieces such as this were made in Chine and were very popular in the 1920s/30s. A bit of patina brings out the beauty!
