The cylindrical body of the pedestal is shaped from green onyx. It is set on a square onyx base, which sit on four ormolu feet, and is surmounted by a square onyx plinth. The pedestal features two very fine ormolu mounts: an ormolu Corinthian capital at the top of the column, with acanthus leaf decorations, and an ormolu socle at the bottom of the column, which connects to the base.
