Reine de Calcédonia ring, Dior Fine Jewelry ($160,000)

Leave it to Victoire de Castellane and the house of Dior to create an imaginary kingdom more whimsical and extravagant than any in existence or in the era that inspired it some 400 years ago. A collection of 10 kings and 10 queens hold court to complete the Rois et Reines high jewelry collection: dramatic, regal figures whose characters are dictated by the precious stones themselves. The Queen of Calcédonia, her head carved from a single blue chalcedony, commands attention with her theatrical 17th-century costume and crown fashioned from white gold and various cuts of diamonds. Fabiola Beracasa declares it “the ultimate gift for any woman looking to stand out with a little dark mystery.” A ring truly fit for a queen. 21 E. 57th St., 212-931-2950
