All these stones are set in a most expensive manner developed by Van Cleef & Arpels: the Invisible setting. Each diamond inside the square was specifically cut to fit perfectly with the other three in that perfect square. It seems now that somebody who worked for Van Cleef has let the cat out of the bag and let out the secret of invisible setting to the trade. We have a unique, beautiful situation here. Jewelry of this nature tends to sell for between four and five thousand dollars.
