This is a really unusual frame and a style we haven't had before. It is a real piece of sandstone, which has been inprinted with fake fossils, to make it look natural with a geological feel. It is a pale cream sandstone and as such very heavy and has an etched frame which surrounds the aperture to focus the eye. It measures approximately 14.4 inches square and makes a real statment; perfect for a 4x4inch photograph. The front of the frame is rough and un-even and the back of the frame is smooth and very slightly un-dulating.
