The color of a diamond is one important determinant of value. Diamonds actually come in a wide array of colors, but the rarest and most valuable diamonds are "white" or colorless. A diamond's color is given a letter grade beginning with D (absolutely colorless) and proceeding down the alphabet depending on how much they deviate from the purest "white."
Clarity describes how perfect the stone is. If there are detectable internal imperfections or external irregularities made by nature in the formation of the diamond, then it is less valuable. These flaws are called inclusions. Inclusions are undesirable because they interfere with the light passing through the diamond causing it to have less brilliance. Clarity is graded on a scale from internally flawless (IF) to included (I). To be give a grade of flawless, a diamond must have no inclusions visible to a trained eye under a 10x magnification.
The cut is literally how the diamond was cut. There are many different shapes, but round brilliant is the most common. The cut is determined by a mathematical formula for each diamond to maximize the brilliance and fire of the diamond.
Carat is a unit of measurement for a diamond's weight. One carat is equal to 200 milligrams. It is important to take cut, color, and clarity into the equation for a large diamond with a bad cut and poor clarity and color will be much less valuable then a smaller, higher quality one.
