&quot;Niarchos Ruby Sautoir&quot; Made by Van Cleef &amp; Arpels, this double-strand sautoir was a present to princess Sophie of Greece from the millionaire Stavros Niarchos when she married in 1962 King Juan Carlos I of Spain. The sautoir can be divided into three parts (a long necklace and two shorter ones) which may be worn in several ways : as a bracelet, as a collar necklace or as a bandeau tiara.
