The ring from the Madame collection is a statement of absolute elegance, where purity of design meets depth of colour. Crafted in 18kt white gold, it stands out for its luminous band covered with a pavé of diamonds that diffuses light with refined continuity. At the centre, an intense emerald-cut blue sapphire catches the eye with its deep shades, a symbol of wisdom, strength and harmony. The essential line of the ring enhances the central gem, which emerges as the protagonist in a perfect balance between rigour and sensuality. The discreet yet decisive elegance of this Casato jewel celebrates a modern and self-aware femininity, capable of transforming every gesture into a reflection of light and character.
