The designs in the Cartier Paris Nouvelle Vague jewelry collection (www.cartier.com) either obviously or subtly reference the jewelry house’s home city. One of the collection’s motifs features curvaceous diamond-studded wave patterns intended to evoke the ripples of the Seine. Another references the city’s 1930s architecture with graphic shapes and subdued gemstones. The ring shown here is adorned with strands of gold beads that appear to burst from the band like fireworks launched into the night sky. The collection ranges from gold designs to pieces featuring striking layers of onyx, lapis, and diamonds. Prices start at $2,740.
