Diamond Screeners and Testers
Screening vs. Testing
Protecting the integrity of your inventory is paramount. Understanding the differences between testing and screening while using the topmost instruments for each process will best protect your reputation. View Stuller's Diamond screening policies.
What is Screening?
Screening is the process by which natural diamonds are separated from lab-grown diamonds. Since it’s impossible to identify a diamond’s growth origin by sight alone, screening equipment is the surest way to determine whether a diamond is natural or lab-grown. Furthermore, screening is distinctly different from detection (or testing), which involves positive identification of a diamond, lab-grown diamond, or simulant.

Testing is the process by which diamonds are definitively separated from created Moissanite and other simulants.Testing instruments typically separate stones based off of their thermal and electrical conductivity, but they have limits. Learn the limitations of your tester and know when to bring in another device (or send it off to a lab with more advanced equipment).
