Enter the color grade, weight in carats, quality, and depreciation factor into the calculator to determine the value of the emerald.

Emerald Value Formula

The following formula is used to calculate the value of an emerald.

V = (C * W * Q) / D


  • V is the value of the emerald C is the color grade of the emerald W is the weight of the emerald in carats Q is the quality of the emerald (including factors like clarity and cut) D is the depreciation factor (which accounts for age and condition)

To calculate the value of an emerald, multiply the color grade by the weight in carats, then multiply the result by the quality factor. Divide this result by the depreciation factor to get the final value of the emerald.

What is a Emerald Value?

Emerald value refers to the worth or price of an emerald gemstone, which is determined by factors such as its color, clarity, cut, and carat weight. The most valuable emeralds are those with a vivid green hue, high clarity, and good cut. The size of the emerald, measured in carats, also significantly impacts its value, with larger stones generally being more valuable. Other factors that can influence an emerald’s value include its origin and whether it has been treated or enhanced in any way.

How to Calculate Emerald Value?

The following steps outline how to calculate the Value of an Emerald using the given formula:

  1. First, determine the color grade of the emerald (C).
  2. Next, determine the weight of the emerald in carats (W).
  3. Next, determine the quality of the emerald (Q), considering factors like clarity and cut.
  4. Next, determine the depreciation factor (D), which accounts for age and condition.
  5. Finally, calculate the Value of the emerald (V) using the formula V = (C * W * Q) / D.
  6. After inserting the values of the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge:

Color grade of the emerald (C) = 4

Weight of the emerald in carats (W) = 2.5

Quality of the emerald (Q) = 8

Depreciation factor (D) = 0.9
