First, The Four Cs

To know the value of a diamond, you must first determine the “four Cs,” which stand for carat, clarity, color, and cut. Carat is the size and weight of the diamond. Clarity refers to the blemishes in the diamond. A diamond without blemishes is “flawless”. The color of the diamond is categorized from D to Z. D meaning colorless, through to Z, the most color. Some shades of the diamond are blue, pink, white, red, and yellow, among others. The red diamond is the rarest. The last C, the Cut, refers to the shininess and manufacturing of the diamond.
