Diamond Cut

Curated and Reviewed by Lesson Planet
This Diamond Cut interactive also includes:
  • Simulations Instructor Tutorial
  • Diamond Cut—Resources
  • Diamond Cut Walkthrough Video
  • Join to access all included materials

How do jewelers tell the difference between diamonds, glass, and cubic zirconia? A sparkling simulation demonstrates how to use a ray of light to determine the substance and ideal shape for a diamond. Scholars control the material, table, crown, and depth for each trial.
