In addition, color is the most obvious feature of the diamond's appearance after its shape. The immediate effect of the combination of color and shape is what demands our attention. It can be generally stated that the higher the color of the diamond, the more rare is that gemstone. Indeed, truly colorless diamonds are extremely rare. To determine a diamond's clarity, it is viewed under 10-power magnification by a trained eye.
Most diamonds contain very small natural inclusions.
The fewer and smaller the inclusions are, the less likely it is that they will interfere with the passage of light through the diamond and the more beautiful the diamond will sparkle. Diamonds, more than any other gemstone, have the capacity to produce the maximum amount of brilliance. Where the inclusions lie, their size, and their type determine the value of the stone. Imperfect - inclusions visible to the eye. Slight inclusions, although they reduce the value of a diamond, do not take anything away from its beauty.
