A deeply covetable piece from one of Brazil's most celebrated artistic dynasties. The bold, organic ring is set with a carved tourmaline cabochon featuring the signature curved, free-form carving within the gemstone — a technique Burle Marx pioneered and called forma livre, meaning free form. The deep blue-green hue known as indicolite is mysterious and alive, shifting in the light like still tropical water. The wide, brushed-gold band grounds the gem, letting the tourmaline speak. Wide and commanding on the finger, it wears as much like a work of art.
