DFI V3: the tool for identifying synthetic diamonds – on display at GemGenève

GGTL Laboratories Switzerland will also showcase the latest version of the DFI, our flagship instrument for analyzing mixed parcels of colorless diamonds, at the upcoming GemGenève fair.

The DFI V3 combines visual inspection, multi-band UV luminescence, low-temperature or room-temperature laser excitation, Raman spectroscopy, and is guided by our proprietary Spect-Ident software. Even non-experts can reach a conclusion without needing to interpret spectra, making detection fast and efficient. The result: a clear and direct identification of natural diamonds, synthetics, or simulants—with no need to send stones to a lab.

With irradiance-calibrated single or dual-channel spectrometers, the DFI offers exceptional spectral resolution and high-speed analysis, even for colored stones.

📍 Come see it live at booth L11, May 8–11, at GemGenève.
