Description
Poster – “CPF technique on screening and ID of DIAMONDS – natural, lab-grown and post treated”
For those interested in adding another screening technique to their daily identification process, cross-polarized filters (CPF) can offer a way to distinguish between natural and lab-grown diamond as one of the more inexpensive and simplest methods. Learn to identify a diamond’s strain pattern and how it correlates to its origin. Think of CPF as a way for each diamond to tell you its story of how it formed and the stresses it experienced during and after crystal growth.
The poster is laminated on both sides.

Poster: Steps in Screening and ID of Lab-grown Diamonds
This poster illustrates the steps for checking if a diamond is synthetic using both basic and advanced instrumentation. The flowchart is accompanied by images showing the main analyses that can be performed, such as those relating to fluorescence and birefringence. It is ideal for appraisers, gemmologists, and jewellers.
