Inspiration - Van Cleef & Arpels Zip Necklace

The suggestion for the design of the iconic Van Cleef & Arpels Zip Necklace came from life long customer, the Duchess of Windsor, Wallis Simpson.  She was known for her amazing jewelry collection, an auction of twenty pieces was held in 2010. She suggested a convertible necklace made in a zip fastener style. In 1951 the zip necklace was created.  The design appeals to my desire to have items that perform double duty.  The necklace transforms into a bracelet (see video below).

I wish that someone would create a less expensive version of this amazing piece but I have yet to find anything similar. It's stunning. Van Cleef & Arpels has created many versions of this necklace over the years in different metals and with various gems.  All unique in their own way.

Is their an iconic piece of jewelry that you love and wish to own?
