Each of these clocks is made from a real polished naturally coloured slice across an agate stalactite. The hands can be moved with care to set the time of your choice. The back of each clock is flat so they can be easily secured to a wall if desired. The centre clock has translucent centre but also a couple of hairline cracks within the agate, which can be hidden by the clock hands. This is reflected in the price. The second and third photos show the cracks and how they can be obscured. The stands are not included.
