Calculating the weight of a diamond is essential in the world of gemology and jewelry. The Gemological Institute of America (GIA) is a renowned authority when it comes to grading diamonds. This Diamond Weight Calculator, designed according to GIA standards, will help you determine the carat weight of a diamond quickly and accurately.
Formula: The carat weight of a diamond is calculated by multiplying the carats by 200. It’s a simple formula used by GIA for estimating the weight of diamonds.
How to Use: To use the Diamond Weight Calculator GIA, follow these steps:
- Enter the carat weight in decimal form (e.g., 0.50 for half a carat).
- Click the “Calculate” button.
- The result will be displayed in carats.
Example: Let’s say you have a diamond with a weight of 0.75 carats. Input this value into the calculator and click “Calculate.” The result will be 150.00 ct, indicating that the diamond weighs 0.75 carats.
