Since aquamarines are available in large sizes, there is no incremental increase in value per carat for large gems.

The IF function is one of the most popular functions in Excel, and it allows you to make logical comparisons between a value and what you expect. So an IF statement can have two results. The first result is if your comparison is True, the second if your comparison is False.
You can use a similar if-then function to color the cells in Excel. Although this feature does not necessitate entering the function IF, the function is identical. Highlight the cells that you want to apply conditional formatting to. You can do this by clicking and dragging your mouse across the cells.
