An ode to the rare color of this Madagascar sapphire with reflections as changing as those of the sky on the sea: from blue to green, from green to blue, through shades of yellow. The radiant gold details that chisel the body of the ring and dress the closed setting recall the brilliance of the sun, sublimating the multicolored aura of this exceptional stone. This ring is made of 18K yellow gold. It is set with a sapphire of a rare blue-green color of 2.5 ct. Its weight is about 5 g.
