I'd LOVE the Van Cleef and Arpels Alhambra opera length necklace (19 or 20 motifs, I believe it is). Exactly how much would I be looking at for one of these? I don't know if I'll ever have the pleasure of owning one or not, but I was just curious if I should ever consider it as a possibility and save for one or if it was completely out of reach. Thanks!
