Authentic Re-Creation of Natural Diamonds
Fourier transform infrared spectroscopy (FTIR) is used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas from different materials. It is a process used by the FBI and various laboratories and scientists to accurately identify the chemical make up of many substances including diamond. It is widely known that diamond is a special crystallized form of carbon. FTIR can differentiate between the two types of natural diamond and the following spectral graphs are definitive and proof positive that Phire diamond is a type two diamond. Type two diamonds have statistically no nitrogen impurities trapped within the diamond structure and are a purer form of diamond than type one. Diamonds with nitrogen impurities trapped internally are known as type one diamonds and represent 98% of all diamonds mined. Approximately 2% of all natural diamonds are type two diamonds and they are the rarest type of natural diamonds. A Phire diamond is therefore a type two diamond comprised of nearly 100% carbon atoms with minute traces of hydrogen, nitrogen, and other gases exactly like a natural diamond.

FTIR of a Type Two Natural Diamond
This is a graph of a Fourier Transfer Infrared Spectroscopy analysis of a natural type two diamond. The resulting wave shape is definitive proof that the gemstone is diamond. The wave shape from 3000 to 1500 wave numbers is the identifier for the element carbon. All natural type two diamonds have this wave shape.
FTIR of a Phire Diamond
This is a graph of a Fourier Transfer Infrared Spectroscopy analysis of a Phire diamond. The resulting wave shape is definitive proof that Phire diamond is in fact a type two diamond. The wave shape from 3000 to 1500 wave numbers is the identifier for the element carbon. All Phire diamonds have this wave shape.
FTIR Comparison of Diamond Imitations
The most common diamond imitations are cubic zirconia (ZrO2) and moissanite (SiC). Here is the FTIR spectra of a pure type two diamond (blue curve), cubic zirconia (green curve) and moissanite (red curve) in one graph. The differences between these specific spectral patterns is obvious. FTIR clearly distinguishes diamonds from all imitations. The resulting wave shape proves that a Phire diamond is in fact a diamond, and an authentic re-creation of a natural diamond. A Phire diamond is not a cheap imitation.
