With more than 200 types of gemstones known to man, it is common knowledge that the most precious gemstones in the world are diamonds, rubies, sapphires, and. Minerals and gems are classified by their physical properties, including hardness, luster, color, density, and magnetism. Different trace elements can produce other colors, allowing beryl to form semiprecious stones such as aquamarine. The color comes from additional traces of chromium and vanadium.
Emeralds are formed of a mineral called beryl whose chemical formula is a complex mix of beryllium, aluminum, silicon, and oxygen.Corundum also forms sapphire in many colors, which generally come from trace mixtures of iron, titanium, and chromium.

Rocks themselves are made of clusters or mixtures of minerals, and minerals and rocks affect landform development and form natural resources such as gold, tin, iron, marble, and granite.
