Fourier-transform infrared spectroscopy is a technique used to obtain an infrared spectrum. This technique shines a beam containing many frequencies of light at once and measures how much of that beam is absorbed by the sample. Next, the beam is modified to contain a different combination of frequencies, giving a second data point.
Depending on the gemstone species and variety FTIR provide us information about the identification of mineral, its genesis, thermal enhancement detection in corundum, filler enhancement in beryl, corundum, spinel, and much more…
An analytical technique used for the elemental analysis or chemical characterization of a sample. It relies on an interaction of some source of X-ray excitation and a sample. Its characterization capabilities are due in large part to the fundamental principle that each element has a unique atomic structure allowing a unique set of peaks on its electromagnetic emission spectrum.
EDXRF enable us to see trace element present in the chemical composition of a mineral. Thanks to this trace element we can confirm the identification of a mineral, detect enhancement and associate its corresponding geological origin
Photoluminescence (abbreviated as PL) is light emission from any form of matter after the absorption of photons (electromagnetic radiation). It is one of many forms of luminescence (light emission) and is initiated by photoexcitation (i.e. photons that excite electrons to a higher energy level in an atom). A laser (532nm) passe trough the gemstone, its absorption allowed us to identify a mineral variety, and in some case enhancement detection, such as thermal treatment in spinel.
Raman spectroscopy is commonly used in chemistry to provide a structural fingerprint by which molecules can be identified.
The laser light interacts with molecular vibrations, phonons or other excitations in the system, resulting in the energy of the laser photons being shifted up or down. The shift in energy gives information about the vibrational modes in the system. Raman provide us with a reliable identification of a gemstone variety and specie
Ultraviolet–visible spectroscopy uses light in the visible and adjacent ranges. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. It measures the intensity of light passing through a sample, and compares it to the intensity of light before it passes through the sample. Uv-vis provide us not only with chemistry information and trace elements but more importantly with the one playing a role within the color of a gemstone, information extremely relevant for origin determination.
3D Scan system for the accurate geometrical measurements of polished and semi-polished diamond and gemstone.
The scan provide us and you with accurate cut analysis, each angles of each facets, proportions and dimensions. Very useful for gem cutter and Jeweler as you can download the .stl file and create your jewelry directly around your jewel
Micro-Photography is present in our "Collector" Report and pinpoint keys features present in your gemstones, it can help for identification, re-identification, enhancement detection and origin determination
Magnification (from 20X up to 5000X ) through microscope is the most important tool.
Enabling us to reliably identify a gemstone, its enhancement, and its origin determination. high resolution of internal features present in your gemstone is the major key for all conclusions present on our Reports.
Laser-induced breakdown spectroscopy is a type of atomic emission
it can analyze any matter. It operates by focusing the laser onto a small area at the surface of the specimen; when the laser is discharged it ablates a very small amount of material, which generates a plasma. At this point the characteristic atomic emission lines of the elements can be observed. Our LIBS is use for light elements detection, It provide clue for origin determination, and light element diffusion (such as Beryllium and lithium).
Advanced Elemental Analysis
Our Advanced Elemental Analysis Provide us with almost all element present in the periodic table. Thanks to our new analysis we are now able to give you access to semi quantitative chemical analysis of your gemstone. Extremely valuable information for identification, enhancement detection, and origin determination.
UV imaging & IR imaging
Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum and produce images of that radiation. Ultraviolet photography is a photographic process of recording images by using light from the ultraviolet (UV) spectrum only. Images may reveal structures not apparent under visible light. In our perpetual quest for consistency and precision UV & IR imaging offer us visual clue for filler in gemstone. Great help for quantification.
