Nubian Germs is s the authoritative gemstone testing facility in Tanzania. We have been using Renishaw’s high performance confocal Raman microscopes to perform non-destructive identification and characterisation of gemstones, such as tanzanite and diamond.
In addition, Renishaw’s inVia is used in crystal defect research, gem inclusion analysis and determining whether gem fissures have been filled. inVia is an ideal tool for the analysis of beryl, in which there are many solid, liquid and gas phase inclusions. A combined spectrum of these inclusions and beryl base is obtained, from which the constituents can be identified from a database of liquid and gas reference spectra.
