The 4 C's are the four key factors that influence the quality and value of diamonds. They are Carat, Cut, Clarity, and Color.
Carat is the unit of measurement for the weight of a diamond. Generally, larger diamonds are more valuable than smaller diamonds, so the higher the carat weight, the more expensive the diamond.
Cut is the most important factor in determining a diamond's brilliance and fire. A well-cut diamond will have maximum brilliance and sparkle, while a poorly-cut diamond will look dull. A diamond's cut grade is based on the diamond's proportions, symmetry, and polish.
Clarity refers to the presence of inclusions and blemishes within the diamond. The fewer inclusions or blemishes, the higher the clarity grade, and the more valuable the diamond.
Color is another important factor that affects the value of a diamond. Diamonds range in color from colorless (the most valuable) to light yellow or brown. The color grade is based on the amount of yellow or brown color present in the diamond.
Overall, the 4 C's are essential factors that influence the quality and value of a diamond. By understanding and considering the 4 C's, you can ensure that you get the best possible diamond for your budget.
