GLOBAL CONSULTATION & CERTIFICATION INTAKE
Excellence in Analytics
Our laboratory is equipped with world-class analytical tools to ensure the highest standards of precision in gemstone research and certification.
PRELIMINARY ANALYSIS
The foundational pillar of our laboratory. These precision instruments allow
for the essential initial assessment of every specimen that enters PGGL.
Purpose: Examination of inclusions, treatments, clarity characteristics, natural vs synthetic identification, and origin indications.
Measures refractive index (RI) and birefringence, which are among the most important properties for gemstone identification.
Determines optical character, singly or doubly refractive nature, strain patterns, and optic sign.
Studies absorption spectra and helps identify gemstones and coloring elements.
Detects pleochroism and assists in identifying colored gemstones.
Purpose: Used as a supporting test for emeralds and certain colored gemstones.
Detects fluorescence and assists in gemstone identification and treatment detection.
Measures specific gravity (SG), an important physical property for gem identification.
Initial examination of inclusions, polish, symmetry, and surface features.
ADVANCED SPECTROSCOPY
Our advanced analytical wing utilizes quantum-level physics to determine chemical compositions and detect treatments invisible to traditional gemological tools.
Detection of gemstone treatments, diamond type classification, and identification of fillers, oils, and polymers.
Advanced identification of gemstones and mineral inclusions.
Analysis of trace elements, color-causing agents, and treatment detection.
Advanced diamond and colored stone analysis.
Determines chemical composition and trace elements.
Energy Dispersive X-Ray Fluorescence determines precise chemical composition and detects critical trace elements for origin verification.
Every stone undergoes mandatory primary testing with our core gemological suite to establish its basic identity and properties.
If ambiguities remain, the specimen is moved to the molecular lab for detailed spectral analysis and chemical fingerprinting.
Data is cross-referenced with our internal database and global standards before being certified by at least two senior gemologists.
Trust the equipment, rely on the experts. Experience the gold standard in gemological certification.
