# The property card

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

Five questions on lesson 2 of Diamond vs moissanite. 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: Which number explains why moissanite shows more fire?
  ### Show the answer
  **b**: Dispersion is how widely white light spreads into colors.
2. Question 2: Why does moissanite have two refractive indices?
  ### Show the answer
  **a**: The two rays travel at different speeds, so each has its own index.
3. Question 3: Mohs hardness 9.25 vs 10 means…
  ### Show the answer
  **b**: Mohs ranks scratch resistance. It doesn't measure the size of the gaps. Chipping is toughness, a different property.
4. Question 4: In the [simulator](https://digitalgemology.com/tools/3d_gemstone_simulator), you switch from diamond to moissanite without touching the carat. Which line at the top of the report changes, and why?
  ### Show our answer
  Measurements: moissanite is lighter for its size, so 1.00 carat of it is a bigger stone.
5. Question 5: A thermal tester beeps "diamond". Which line of the card tells you that isn't the end of the story?
  ### Show our answer
  Heat conduction: moissanite's is close enough to diamond's to pass the test.
