Hello, this is my first post. I really need to find the price of 2 original Van Cleef and Arpel Alhambra necklaces, 32 in each, one is onyx and one is mother of pearl. They belong to a friend of mine and she needs an aproximate cost, as she is getting divorced. I would really appreciate some help. i''ve scoured the web and called Van Cleef but they were tight lipped.
