Gemstone Earrings are made of gemstones which are also called gems in short. A gemstone is a mineral that is transformed into a major component of an article of jewelry after going through many industrial processes like polishing and cutting. There are many kinds of gemstones. For instance, although Lapis Lazuli is not a mineral but an organic material is also regarded as a gemstone. Again, some gemstones are soft and are still used in jewelry as they are lustrous. Diamonds, emeralds, sapphires and rubies are the most demanded for being precious gemstones while amethyst, agate, jasper and the rest are seen as semi-precious stones.

Value of a gemstone depends on whether the stone or mineral is colored or not and are graded according to this. Value likewise depends on how well the gemstone is cut. It is the most important determinant of the prices. Although gemstones are graded according to their being precious or semi-precious, the price still depends largely on the brand name.

There are some gemstones that are used as jewelry like Gemstone Earrings in the exact form in which they are found, although more often these gemstones too have to go through the industrial purification process of polishing and cutting. Among gemstones two broad classification groups are the cabochons that are dome shaped and smooth, and the gemstones that are industrially cut by using a Faceting Machine what polishes the small facets of the gemstones causing them to increase in brilliance which happens when the light entering into them increases. This process is important as it greatly increases the value of the gemstone. For example, the gemstones that are cut and used as cabochons are variscite, opal turquoise and other. These gemstones especially decorative items as they show the color of the stone. These are industrially polished with the help of grinding wheels and other polishing agents. This is done to polish the surface of the gemstone, to shape its surface and to grind it for removing impurities.
