This rare Cartier Paris aquamarine brooch with its bold diamond chevron patterning dates from the 1930s, when designers created a dynamic series of jewels that featured these limpid blue gems from Brazil. Set in minimal platinum, the aquamarines icy blue depths were juxtaposed with the intense sparkle of brilliant- and fancy-cut diamonds, set in strong directional patterns that are perfectly Art Deco. Leave no doubt about your dedication to bejeweled modernism with this Cartier art classic, which is easily clipped to the strap of an asymmetric gown or high neck sleeveless dress.
