This 2-strand necklace is made with both strands being removable so each strand can also be worn separately. The top strand measures 16 inches and is made with medium silver cable chain, small silver 3-D heart charms and super sparkling 5mm AB (aurora borealis) crystal rhinestone in silver casing dangle charm. The bottom strand measures 20 inches long and is made with thinner silver cable chain and a larger silver open heart charm/pendant. Each necklace strand has a lobster claw clasp on each end and when worn together, clip onto the back connector, which is made of 2 larger jump rings and a lobster claw clasp. That means two necklaces in one! See pictures for reference. All materials are silver plated, nickel free and lead free.
