Refined brilliance with a touch of Parisian charm.
The Cosette captivates with its balance of elegance and modern sparkle. A radiant-cut diamond, known for its perfect fusion of fire and symmetry, is gracefully set in a four-prong pavé band. Each micro-set diamond along the shank enhances the centre stone’s luminosity — a timeless ode to sophistication and romance.
