They say that everything in the world is either plant, animal or mineral. The minerals make up all of the nonliving matter on the earth and the science of mineralogy studies these bricks of which the earth itself is made. Artist Jeff Scovil utilized the graphics from his artwork entitled "Minerals of the World" on this microwave and dishwasher safe coffee cup. It features ten minerals from around the world including Quartz, Gold, Azurite, Pyrite, Emerald, Beryl, Rhodochrosite, Fluorite, Mimetite and Tourmaline all shown in color against a map of the world. The mug also gives the country of origin for each of the ten minerals. This would a great gift for the rock hound or naturalist in your family.
