Color is the vital thing that should be considered when buying a gemstone. The brighter, richer and more vivid the color, the more valuable the stone. Gems should be observed in different lights. Some gems look magnificent under florescent lights, but appear lifeless in daylight, or vice versa.
Clarity is determined by the number, size, nature, and location of the inclusions and blemishes imperfections of a gemstone. Only glass or rare gems of very high value have no inclusions visible to the naked eye. Although it is difficult to find gems without flaws, try to avoid those with lots of inclusions that are obvious when the gem is viewed face up and those with cracks that reach the surface.
