"MONUMENTAL 'TOURBILLION' BROOCH"
(French. ca. 1937)
A rare and important brooch by the esteemed French modernist jewler Suzanne Belperron, executed on a monumental scale. A variation of the designer's iconic "Tourbillion" (swirl) or "Corde" (rope) designs crafted from 18k yellow gold and platinum, accented by 27 graduated transitional round brilliant and single-cut diamonds. The brooch has sensuous ribs, almost reminiscent of the coil of rope, outlining an exuberant, seeping curved form which occupies multiple planes in space. The overall effect is one of dynamic motion. The diamonds appear to be, on average, in the "G" or "H" range in color and the "VS" to "SI" range in clarity. The piece bears French assay marks for 18k gold, as well as a maker's mark for the workshop of Groene et Darde.
(The color and clarity grades of the diamonds are estimated, as they were not examined out of mounting)
