Beauty, durability, and rarity: such are the three cardinal virtues of a perfect gemstone. Stones lacking any of them cannot aspire to a high place in the ranks of precious stones, although it does not necessarily follow that they are of no use for ornamental purposes. That a gemstone should be a delight to the eye is a truism that need not be labored; for such is its whole raison d'etre. The colors that are most admired - the fiery red of ruby, the royal blue of sapphire, the verdant green of emerald, and the golden yellow of topaz are purest chromatic tints, and the light absorption spectra corresponding to them are on the whole continuous and often narrowly focused. Our Gemstone encyclopedia has nearly everything you always wanted to know about the mysterious world of gemstones. The Internet is about information, and we want to provide you with all the information you will need on both the common and some less common gems. Any of these lesser known stones may suddenly spring into prominence owing to the choices of fashion or perhaps a stone may figure at some royal wedding; when it is in the spotlight for a brief while it becomes the vogue, and afterwards is seldom seen, even though its beauty remains constant. Our gemstone encyclopedia is one of the most extensive information sources on the internet, as we want our customers to be comfortable and knowledgeable concerning their purchases. Above are gem specific and informative pages of information on each individual gemstone, and below on this text are the answers to a number of common questions about gemstones in general.

The gem minerals are those which, on account of certain physical characters, are regarded as objects of beauty, and are used for personal adornment or other ornamental purposes. Color, refractive index, dispersive power, hardness, transparency, and the absence of inclusions, are as a rule the chief physical factors determining the qualities of gemstones. The value of the stones, however, depends largely on  their rarity. Most gem minerals are highly transparent and variable in color. This variability is well exemplified in the several color varieties of the mineral corundum, of which the best known are the ruby (red), and the sapphire (blue and other colors). The diamond is a unique instance of a generally colorless gemstone in which the qualities of hardness, refractive index and dispersive power are all developed to an extremely high degree. In some instances, non-transparent minerals are used as gemstones. These types of stone possess an attractive color gives a value in the absence of transparency. Some examples include turquoise, precious opal, jade, jasper and some other forms of silica, malachite, and pyrite may be mentioned. Gemstones as a whole show a wide range of chemical composition. The diamond is unique chemically as it is physically, for it is the only natural gemstone consisting of a single element. Many of them are oxides, such as ruby, sapphire, amethyst and other forms of silica. A large number are
silicates, like garnet, olivine, emerald, and tourmaline. Other types such as carbonates (malachite, azurite, and calcite), phosphates (turquoise and apatite) and fluorides (fluorite) are also represented.
