Using the Ideal Scope for Diamonds
The Ideal-Scope is an awesome tool for measuring the cut quality of a diamond. It shows how much light the diamond reflects and is a great visual example of judging the brilliance of a diamond.

This is an example of a very good diamond. Red indicates light that is reflected back, and white shows light leakage. More red is better, so this is a well cut diamond.

Notice all the white spots. This means that a lot of light is being lost inside the diamond, and it won’t be as brilliant as a better cut diamond.
You can see more information at the official Ideal-Scope website, including their Ideal-Scope reference chart.
James Allen has a collection of Hearts and Arrows diamonds, and they have Ideal-Scope images of all their diamonds in this collection.
