Fourier Transform Infrared (FTIR) Spectroscopy

 

Diamond Type Detection

Diamonds are classified into types Ia (IaA-IaB), Ib, IIa, and IIb, Based on the presence, concentration, and atomic configuration of impurities—primarily nitrogen and boron—within the carbon crystal lattice. This classification is determined through infrared (IR) spectroscopy. Since most synthetic diamonds belong to Type II (which contain little to no nitrogen), determining the diamond type can significantly aid in identifying its authenticity. Therefore, diamond type analysis helps assess whether a diamond is natural or laboratory-grown (HPHT or CVD).

 

Emerald Authenticity & Treatment Analysis

 

Verification of natural origin and identification of clarity enhancements. Precise detection of foreign substances within surface-reaching fissures is achieved using FTI spectroscopy, which distinguishes between polymers (resins) and oils used to fill fractures by identifying their unique spectral ‘fingerprints’.

 

Qualitative Mineral Identification

Rapid identification of unknown gemstone species by comparing their spectra against extensive reference libraries.
