Antique Large Cannetille Filigree Silver Lapis Lazuli Cabochon Pendant Necklace

Beautiful example of Cannetille silver filigree with a large lapis lazuli cabochon centre. 

This is an antique piece so it has some age related wear but it’s structurally sound. Minor flaws on the lapis but it’s not cracked. They are surface flaws on the back. Fully tested as silver but I don’t know the grade of silver. The chain is more modern and marked 925 on the clasp as shown. 

Large size as seen in the pictures and the sterling silver chain measures at 16 inches in length.
