My necklaces are approximately 16 to 18 inches in length and have a 2 inch extender chain. They are made with sterling silver components and chain. All the wire used in the jewellery is silver plated with an anti tarnish coating. Most of the necklaces, bracelets and earrings can be made with 14k gold filled components. If you would prefer a different length necklace or different materials to be used please let me know.
