Clarity is determined by placing the diamond under 10X magnification. However, cut is most important for the value of a clear diamond, because without the proper cut, the diamond will not sparkle, as it should. Clarity and color are next in importance. All other gemstones grade on 20/20 vision with the naked eye. The quality of all colored gemstones, together with colored diamonds, is based on the clarity and brilliance of the stone’s color, which is further divided into three parts: *hue*, *saturation*, and *tone*. Hue refers to the stone’s color, which produced in the following spectral hues: red, orange, yellow, green, blue, violet, purple and pink. Purple and pink are spectral hues, as purple lies halfway between red and blue, and pink is really a lighter shade of red. Natural stones seldom have pure hues, so these are into primary, secondary, and sometimes tertiary hues. Saturation refers to the clarity of color, or the stone’s freedom from brown or grey hues.
