Our Technological Arsenal & Research Instrumentation

 Laboratoire Gem Québec maintains a world-class analytical infrastructure, providing non-destructive expertise for the most precious gemstones.

Advanced Spectroscopy & Chemical Analysis (Trace Elements)

For the identification of treatments and geographic origin, we utilize state-of-the-art molecular and atomic spectroscopy:

• LA-ICP-MS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry)

• Raman and Photoluminescence (PL) Spectrometers

• FTIR (Fourier Transform Infrared Spectroscopy)

• UV-Vis-NIR (Ultraviolet-Visible-Near Infrared)

• EDXRF / WDXRF (X-Ray Fluorescence)

• LIBS (Laser Induced Breakdown Spectroscopy)

Scientific Imaging & X-Ray Radiography

We explore the internal structure of gems and pearls for seamless authentication:

• Micro-CT / X-Ray Tomography (High-resolution 3D visualization)

• X-Ray Radiography and Cathodoluminescence

• SEM-EDS (Scanning Electron Microscopy)

• EPMA (Electron Microprobe)

• High-resolution Photomicrography and Video Endoscopy

Specific Diamond Expertise (Natural vs. Synthetic)

We secure your diamond investments through the strictest screening protocols (CVD/HPHT):

• DiamondView and DiamondSure (De Beers Group)

• DiamondCheck, DiamondDock, and Diamond Dossier screening instruments

• Thermal and Electrical Conductivity Testers (Diamond / Moissanite)

Classical Gemmology & Precision Instruments

The foundation of all expertise rests on a perfect mastery of optical and physical tools:

• Microscopes: Stereoscopic, immersion, and polarized.

• Optics: Refractometer (RI 1.81), Polariscope, Conoscope, Dichroscope, Chelsea and Hanneman/Hodgkinson filters.

• Lighting: Darkfield, diffuse, oblique, fiber optic, and UV cabinet (Short/Long wave).

• Physics: Analytical and hydrostatic balances (Densimeter), precision gauges, and Master Stones.
