Sapphires are commonly worn as jewelry in which vary range of custom made jewelry and sapphire custom made jewelry is most the popular nowadays. Sapphires can be manufactured for industrial or decorative purposes in large crystal boules. Because of the remarkable hardness of sapphires, sapphires are used in some non-ornamental applications, including infrared optical components, such as in scientific instruments; high-durability windows; wristwatch crystals; and very thin electronic wafers, which are used as the insulating substrates of very special-purpose solid-state electronics.
The value of sapphire depends on their size, color and transparency. However, it is not the only criteria to do the judgment but the origin of the gem is also playing a major role which explains the great differences in price between the various qualities.

If the stone selected then happens to be a genuine, certificated Kashmir or Burmese, the price will probably reflect the enthusiasm of the true gemstone lover. Since then, top-quality sapphires, however, remain extremely rare in all the gemstone mines of the world.
A rare variety of sapphire which is known as color change sapphire, exhibits different colors in different lighting. Color change sapphires are blue in outdoor light and purple under incandescent indoor light; they may also be pink in daylight to greenish under fluorescent light. Some stones shift color well but others only partially and all you can find at wholesale jewelry findings.
