Developed in collaboration with scientists from the University of Basel, this portable spectrometer is a powerful gemmological tool. It can be used for various in applications for coloured gemstones, but this model is not useful for diamonds. Conceived specifically to resolve gemmological questions, this is a cost-effective solution that combines absorption, transmission and luminescence spectrometry. It is simple to use and highly mobile offering a USB port connection to any laptop computer.
How can the SSEF portable Spectro be used for gemstone analysis?
- Detection of copper in blue tourmaline (Paraiba-type or not?)
- Distinguish Fe-bearing rubies from Fe-poor rubies (e.g. from Burma)
- Distinguish Fe-bearing emeralds (e.g. Brazil and Zambia) from Fe-poor emeralds (e.g. from Colombia)
- Detection of green dye in jadeite
- Detection of chromium in green jadeite
- Indication of origin of sapphires
- Diamond spectrum (e.g. Cape Ia diamonds)
In luminescence spectrometry mode:
- Distinguish natural and flux synthetic red spinel
- Analyze diamond luminescence
- Analyze fluorescent fissure fillings, e.g. polymer treated jadeite (B-Jade)
- Register chromium in sapphires below XRF detection limit and a number of other applications
