The Madame ring with blue sapphire is a tribute to the quiet power of elegance. Its simple, modern design highlights the central blue sapphire, which, deep and intense like a solo in a grand opera, stands out at the centre of the stage. The minimalist design of the jewel leaves room for the expressiveness of the precious stone, which, like a diva, takes its place in the spotlight. The Madame collection celebrates the theatricality of jewellery, alternating charismatic protagonists with harmonious details. Casato creates jewellery to be worn every day and dedicates it to those who love to stand out with composed and refined beauty.
