The Bonheur solitaire features a round diamond, ranging from 0.30 to 3 carats, reflecting the Maison's tradition of excellence. It is selected according to the most exacting standards to ensure the brilliance of the creation. The precious stone is delicately held in place by a prong setting on a timeless mount. The platinum ring is mirror polished, one of Van Cleef & Arpels’ emblematic techniques, enhancing the luminosity of the precious metal.
