# Cut grade or light performance: what "Ideal" means

Lesson quiz · five questions, in a new order every time

Five questions on lesson 4 of Reading a grading report. The questions and the answers to pick from come in a new order every time you start.

Pick an answer, and the question marks itself. For a question that you answer in your own words, think of your answer first. Then show our answer and say whether you had it. Nothing is saved or sent.

1. Question 1: A GIA report's cut grade line reads "Ideal". What's wrong?
  ### Show the answer
  **b**: GIA's cut grade runs Excellent to Poor.
2. Question 2: What does "Ideal Cut Round Brilliant" in IGI's comments tell you?
  ### Show our answer
  It's an Excellent cut grade, and every proportion sits inside IGI's narrower middle band.
3. Question 3: Which stones can get an AGS Ideal Report by GIA?
  ### Show the answer
  **b**: And even many Triple Excellents don't make it.
4. Question 4: On an ASET map, what does gray mean?
  ### Show the answer
  **b**: Light that leaks out instead of returning.
5. Question 5: A round has a 41.4° pavilion and otherwise T73 proportions. What would our tool say, and would it fit IGI's Ideal band?
  ### Show our answer
  The tool says Excellent. IGI's band ends at 41.3°, so it wouldn't get the Ideal comment.
