Rare CHAN LU Black and Cream Necklace

Rare CHAN LU Black and Cream Necklace; Necklace has Alternating Faceted Dark Beads with Double Small Cream Beads Embellished with an Approximately 3" Natural Stone; Heart Shaped Piece Near Hook Engraved with "CL" on one side and "925" on the other side. Gently Used Condition, except charm on necklace is tarnished (see photos). The large natural stone on necklace has a rough spot on one side; however, this was present when the necklace was purchased and is NOT considered damage (see last photo). This Necklace coordinates well with the CHAN LU bracelet also listed in my Closet.
