Laboratory Equipment

Advanced instruments ensuring precision and reliability in every analysis

Spectroscopy

Renishaw inVia™ Confocal Micro-Raman Microscope

Integrates a research-grade microscope with a high-performance Raman spectrometer for identifying inclusions in gemstones, supporting origin determination and detection of low-temperature heat treatment.

Spectroscopy

LIBS — Laser Induced Breakdown Spectroscopy

Detects all elements including light elements such as lithium, beryllium and hydrogen, with detection limits from 0.1 to 200 ppm. Essential for detecting beryllium diffusion treatment in sapphires.

Spectroscopy

EDXRF QUANT'X Spectrometer

Precisely quantifies major, minor and trace elements across a wide range of samples, providing elemental profiles that support the determination of a gemstone's geographic origin.

Spectroscopy

FTIR — Fourier-Transform Infrared Spectroscopy

Identifies organic and inorganic materials through their characteristic infrared absorption. Used for distinguishing natural from synthetic emeralds, detecting clarity enhancement, and identifying treatments in corundum.

Spectroscopy

Raman Photoluminescence Spectroscopy

Studies vibrational modes of molecules for fast and reliable gemstone identification, reducing reliance on traditional instruments such as spectroscope, polariscope and refractometer.

Spectroscopy

UV-VIS-NIR Spectroscopy

Measures absorption, transmission and reflection of light over 175–3300 nm wavelength range. Valuable for determining color origin and accurately classifying gemstone varieties.

Spectroscopy

Liquid Nitrogen Cryogenic Testing

Cools stones during spectroscopic analysis to sharpen spectral peaks and improve analytical precision. Essential for separating natural diamonds from CVD- and HPHT-grown diamonds via photoluminescence spectroscopy.

Diamond Testing

DiamondView™

Uses short-wave ultraviolet light to excite fluorescence in diamonds, examining fluorescence color and growth features to determine whether a stone is natural or laboratory grown.

Diamond Testing

DTC Melee Sorting Machine

Advanced automated instrument for rapid screening of small polished diamonds, separating natural diamonds from laboratory-grown diamonds, simulants and stones requiring additional testing.

Diamond Testing

OGI DiaColor — Rough Diamond Colorimeter

Advanced instrument for color grading of rough diamonds, providing consistent, accurate and efficient color assessment to support diamond graders.

Diamond Testing

OGI Scanox — Diamond Scanner

Portable high-resolution scanning and planning system using dual laser scanners and HD cameras for inclusion mapping, optimal yield planning and CutGrade analysis.

Diamond Testing

J-SCREEN Diamond Screener

Advanced desktop screening instrument using photoluminescence and UV-Visible spectroscopy for rapid identification of natural versus laboratory-grown diamonds and simulants.

Microscopy

HRD D-SCOPE+ Dark Field Microscope with Camera

Reveals internal features of gemstones with exceptional clarity. Its dark field illumination directs light from all sides into the center of the stone, highlighting even very small inclusions without unwanted surface reflections — a valuable instrument for both gemstone examination and photomicrography.

Microscopy

HB Signifeye Dark Field Microscope

A stereo microscope focused on diamond grading and observation, used from the rough stage through to final polish. Features a dark field LED light, a vacuum pump holder with X-Y manipulation, a special Avalon light for facet quality visualization, and a polarisation option for tension detection.

Microscopy

Gemmological Immersion Microscope

Analyzes gemstones through immersion in liquid with a similar refractive index, reducing surface reflections to make internal inclusions, growth lines and treatment indicators easier to observe.
