Start Your Verification →Gemological Tests We Perform
Every stone submitted to GemVerify undergoes a rigorous battery of scientific tests conducted by GIA-certified gemologists using laboratory-grade equipment. Here's exactly what happens to your stone in our lab.
Spectroscopic Analysis
FTIR & Raman Spectroscopy
Infrared and Raman light beams interact with the stone's molecular structure, producing a unique chemical fingerprint. This identifies the exact mineral composition and detects synthetic or simulant materials with near-perfect accuracy.
Detects
- ◆Synthetic vs. natural origin
- ◆Glass or resin fillers
- ◆Composite stones
Refractive Index Testing
Gemological Refractometer
A calibrated refractometer measures how light bends as it passes through the stone. Every genuine gem species has a precise, known refractive index — deviations instantly flag imitations or treated material.
Detects
- ◆Stone species identification
- ◆Doublets & triplets
- ◆Simulant detection
UV Fluorescence Examination
Longwave & Shortwave UV Lamps
Stones are exposed to both longwave (365 nm) and shortwave (254 nm) ultraviolet light. The color and intensity of fluorescence reveals treatments, coatings, and helps distinguish natural stones from lab-grown counterparts.
Detects
- ◆Heat & fracture-fill treatments
- ◆Surface coatings
- ◆Lab-grown indicators
Microscopic Inclusion Mapping
Darkfield & Brightfield Microscopy (10×–60×)
A gemological microscope at up to 60× magnification reveals the stone's internal world — natural growth patterns, inclusions, and fractures that are impossible to replicate in synthetics. These features also confirm geographic origin.
Detects
- ◆Natural growth features
- ◆Clarity grade (VS, SI, I)
- ◆Origin indicators
Specific Gravity Measurement
Hydrostatic Weighing
The stone is weighed in air and then suspended in distilled water. The ratio reveals its specific gravity — a physical constant unique to each gem species — confirming identity even when optical tests are inconclusive.
Detects
- ◆Precise mineral identification
- ◆Hollow or filled stones
- ◆Density anomalies
Thermal & Electrical Conductivity
Diamond Probe & Thermal Tester
A calibrated thermal probe measures how quickly heat dissipates through the stone. Diamonds conduct heat at a rate no simulant can match; moissanite is distinguished via electrical conductivity — ruling out the most convincing fakes.
Detects
- ◆Diamond vs. moissanite
- ◆CZ & glass simulants
- ◆Synthetic diamond screening
All tests are non-destructive and performed in our ISO 17025–accredited laboratory. Results are cross-referenced across multiple methods before a certificate is issued.
