This important late Art Deco platinum and diamond brooch featuring carved rock crystal, jadeite and emeralds was created by Mauboussin Paris in the period between 1930 and 1935. The brooch centers a green jadeite plaque with white mottling carved to depict a pollinator feeding from a flowering and fruiting plant, framed by faceted rock crystal bars joined by hemispherical fields pav-set with round-cut diamonds, outlined in and highlighted by lines of black enamel, with four carved emerald beads. This rare Mauboussin brooch expresses Parisian avant-garde jewelers profound post World War I interchange with Asian culture, united with the transformative design power of the Machine Age.
