Our Oyster Semi-Flush has a robust charm, its ring of natural oyster shells bursting with seaside tones and textures that glow from within. The simplicity and rusticity of the wrought iron frame that has been treated to a textured bronze finish makes this three-light fixture, which measures 19 inches in diameter by 10 inches high, a kicky lit accent for a seaside cottage or an urban oasis on the waterways.
