    Chemically they are known as "Aluminum Oxide i.e Al2O3". It comes in a gemstone variety of minerals. These are commonly used in jeweleries. For different colors of them they contain some amount of different minerals called impurities in them which absorbs light and thus results in different colors. For e.g. Rubies contain chromium impurities that absorb yellow-green light and result in deeper ruby red color, if some amount of iron are present, a very pale yellow to green color may be seen for blue color presence of titanium and iron impurities is required.
