Perhaps the most magnificent globe in existence, it has a total height of 110 cm. (44 inches) and a diameter of 45 cm. (18 inches) and is covered with over 51 thousand gemstones. The seas and oceans are shown with emeralds. Land masses are mostly displayed in rubies and spinels. Iran, Britain, France, and parts of South Asia are shown in diamonds. The base is constructed of wood, covered with a layer of gold. Approximately 35 kilograms (75 pounds) of pure gold is used in the globe.
