This gorgeous black and white diamond necklace features 1/8 carat of genuine diamonds. The chain is 18 inches and I actually bought the chain separately because I wanted a stronger chain than the one that it was sold with. The chain also has a cute little heart on the lobster clasp. The heart is approx 1 inch tall. The chain and the heart are both stamped 925. Retail price for pendant $349 and chain $79. Brand new. Has been in a box and in perfect condition. Velvet pendant box in photos is included.
