This one-off paperweight belongs to the Gravity Zodiac Collection, a series of twelve pieces celebrating the connection between planets and zodiac signs. The sphere - able to rotate on its base to simulate the movement of celestial bodies - is fashioned of Palissandro Bluette marble, a prized natural stone quarried in Italy and marked by delicate veins emerging from a gray-azure backdrop. The symbol of Pisces associated with Neptune is embossed on the brass base.
