LE BLOC XO "hugs and kisses" rose gold colored necklace NEW

Brand new, never worn adjustable rose gold colored "xo" block charm necklace from Le Bloc. Original retail $108 USD. Some sites list this item as being sterling silver with rose gold plating but please note, I do not see any sterling silver markings on the necklace and I no longer have the paper that was included with the necklace so I can't be certain. The charms can move around freely on the chain. The necklace has a 16" drop with extendable chain up to 18 "
