Make the most of your necklaces and ensure that they can be worn with any outfit you own by investing in some necklace chain extenders. These simple little chains will add 2, 3 or 4 extra inches to your chain length with an easy-to-fit bolt ring clasp to keep them in place. This option is made from rose gold plated sterling silver with a belcher chain measuring 3mm wide, but other chain types and colours are available.
