Cathodoluminescence as a Tool in Gemstone Identification

  • Johann Ponahlo
Chapter

Abstract

The introduction of a method such as cathodoluminescence (CL) in gemmology calls for two prerequisites. First, the new method must be applied non-destructively, furnishing unambiguous results. Second, it has to enable a trained gemmologist to differentiate quickly and accurately between a natural gemstone, a synthetic or an artificial stone.
