Etincelle de Cartier

A band about a millimetre and a half wide, paved with small diamonds and carrying a larger stone in the same line, so the ring reads as one spark.

Joséphine

A diadem shrunk to the finger: a pear-cut stone rising from scrolled arcs, the way an aigrette rises from a tiara.

Etincelle de Cartier is the house's slimmest bridal ring, a pavé band about a millimetre and a half wide with its larger stone set in the same line. Joséphine stands up from the hand: Chaumet's scrolled arcs rise to a pear-cut stone like the aigrette of a tiara, and the line extends to stacking bands meant to be worn together. Cartier keeps everything flat and continuous. Chaumet builds height, the memory of the crowns it made for an empress.
