Christian Dior Knotted Rhinestone Heart Necklace

Chain is original to the piece but the hang tag was broken off. Found the exact necklace on another website to confirm the chain is original. Chain is made well. The heart is hallmarked and seen clearly in the pics posted. No missing stones. Really no finish wear on both. The chain measures 15" long with a 2" extension. The pendant measures 1 1/8" x 1".
