Why Are Some Minerals Classified as Gems?

Answer

Some minerals are classified as gems if they have value for use as adornment. The mineral is classified a gem based on its beauty and how rare it is. Some minerals can form more than one gem, with the color being the chief difference. Rubies and sapphires are an example of this. Both come from the mineral corundum.
