GemRam™

Raman Gemstone Identification System The GemRam™ is a lightweight, portable Raman spectrometer for gemologists and researcher to conduct rapid, non-destructive verification of known gemstones as well as the identification of unknown gemstones based on mineral physics. It comes equipped with B&W Tek’s GemID™ identification software that includes a spectral library of >450 genuine gemstones from the Gemexpert collection, including common and rare gems spectra and images. The GemRam can be used to identify polished Raman Solution

stones, crystals as well as uncut stones.

The GemRam utilizes a frequency-stabilized 785nm diode laser and high resolution TE-cooled spectrometer, providing unrivaled performance and repeatability. For convenient sampling, it comes complete with a fiber optic probe and an X-Y-Z positioning stage, all in a convenient carrying case.
