By using the very latest research grade FTIR, UV-Vis Spectrometers and Microscope Spectra Gem Laboratory detects synthetics and treatments that cannot be detected by standard gemmological equipment used by other gemmologists and gem laboratories here in Australia.
This is especially important because manufacturing and treatment processes are becoming more sophisticated and requires more advanced equipment and testing.
Spectra Gem Reports will not only indicate whether your gem is natural, treated or synthetic but will identify the analysis completed and include the most appropriate data upon reaching this conclusion.
State of the
FTIR Spectroscopy uses an infra-red laser to produce an infrared spectrum that when analysed can determine some or all of the following:
MATERIAL TYPE : Species | Natural | Synthetic
TREATMENTS AND TYPE : Dyes | Resins | Oils | Polymers
ORIGIN OF MATERIAL : What sets the FTIR Spectrometer apart from the standard refractometer is not just the ability to test stones whilst they are set (limitations apply to size and restrictions of settings) but it can detect treatments such as polymer-treated jadeite that standard gemmological equipment can't detect.
UV-Vis Spectroscopy uses varying light sources to produce a spectrum in the visible and ultra-violet areas of the electromagnetic spectrum.
This analysis greatly enhances our ability to identify some specific synthetic gems and treatments.
We use research grade Leica binocular microscope in our analysis. Leica is renowned for being one of the world's leaders in optics. Our microscope allows for 160x magnification, letting us view the smallest features within a gemstone.
Using Leica's 5 megapixel digital microscope camera combined with specialist software, we are able to produce images with the maximum depth of field under the highest magnification to create the sharpest images possible.
A standard Gem report consisting of one or all of the above additional tests is $150.00 Inc. GST.

Limitations of Report
The opinions expressed in the report are provided on careful observation and analytical testing as detailed on the front of the report. The reports cannot take into consideration any developments in treatments and manufacturing techniques of synthetics that have not been recorded or reported in published mainstream gemmological literature and validated by the scientific community at the time of the report. Only the original complete report bearing a signature of an authorised representative of Spectra Gem Laboratory with security features remaining intact shall be deemed authentic. The photograph included on the report is only an indication and is not necessarily a true reflection of colour and size. If gemstone is set all weights and measurements are approximate due to the restriction of the settings.
