Emeralds are gem-quality specimens of the beryl mineral family with a rich, distinctly green color. They are found in igneous, metamorphic, and sedimentary rocks in a small number of locations worldwide. For over 5000 years, emeralds have been one of the most desirable and valuable colored gemstones.

The name grain elevator comes from the method that is used to get the grain to the top. When a truck pulls onto the scale it is weighed, from there the grain gets dumped into the elevator. The grain elevator employee opens the back of the truck and the grain gets poured through a grate into a pipe where it slides down to the bucket elevator.
