A conch pearl, enamel and diamond bracelet is seen at an auction preview at Sotheby's in Geneva yesterday. The bracelet, which once belonged to Queen Victoria Eugenia of Spain (1887- 1969), was made in the 1920s by Cartier and may fetch from 750,000 to 1.3 million Swiss francs (US$800,000 to US$1.4 million) when it goes on sale on November 14 in Geneva.
