We would like to invite you to a presentation on a critical and often overlooked aspect of diamond performance: “Dead Zones vs Dynamic Contrast: Where Is the Boundary of High-Performance Cuts?”
In this session, we will explore:
  • What Dead Zones are and why they reduce visual performance
  • The difference between Dead Zones and High Contrast
  • Why traditional tools (such as ASET) cannot reliably distinguish between them
  • How Dead Zones can be identified, measured, and minimized
  • Practical applications for planning, polishing, and evaluation
The presentation includes real diamond examples, visual comparisons, and a new approach to analyzing performance based on observation conditions.

This is especially relevant for:

Manufacturers and planners

Polishers

Diamond evaluation professionals

We believe this approach provides a clearer and more practical understanding of what truly drives diamond appearance in real-world viewing conditions.
