The Volterra Medium Semi-Flush Mount is a low-profile fixture with a gorgeous shade made from luminous alabaster. The stone diffuses the illumination beautifully while the light that passes through the material reveals its character accentuated by the natural veining that makes alabaster a sought-after choice. The semi-flush is convertible to 13 feet with a chain. The metal frame of the 20-inch fixture and matching finial are in an antique brass finish, and the two-light Volterra is dimmable.
