‘Ideal Cuts’ are rare; in a 1998 GIA study less than 3% of 67,621 diamonds had so called ‘Ideal Cut’ proportions. Why so few? Carat Weight counts more than Cut quality; there is more profit in cutting the heavier diamonds from each rough stone.

Why does the market accept poor cuts?

  1. There is no widely accepted cut quality standard
  2. The best way to grade cut is side by side comparison
  3. But different vendors have different lighting
  4. Diamonds are often traded un-seen

GIA has never graded ‘Cut’ on a diamond report! Cut is complex; the GIA has spent millions and studied Cut for a decade. All Labs that currently grade cut want a better system.The Ideal-Scope is not a grading system, but it is a great portable way to select or reject diamonds. With little or no practice you will reject badly cut diamonds. You can also remember the image quality from one stone to the next. Within an hours practice you could sort 10 diamonds into several cut quality grades.Use the resources on this website to make best use of the Ideal-Scope. With it manufacturers can find how to cut for weight and beauty, retailers can buy and sell better cut diamonds more easily. Consumers can judge for themselves how well cut a diamond is.

The Ideal-Scope Rapid Photography System also sets a universal standard for reliable images.
