How to use Raman spectrometer to authenticate a gem?

Gemstone has unique artistic value and collection value due to its exquisite appearance. Traditional gem identification mainly relies on the experience of inspectors, using magnifying glass, microscope, refractometer, hydrometer and other methods. However, all kinds of shoddy and fake methods in the market have brought great difficulties to the authenticity of gems. In recent years, Raman spectroscopy has become a powerful and even ultimate means of identification in the field of gem identification.

What is the feature of field spectrum?

In the visible and infrared bands, the radiation of surface objects themselves is almost zero. The spectrum emitted by ground objects is mainly reflected solar radiation.  After solar radiation reaches the ground, in addition to reflection, the object also absorbs electromagnetic radiation. 

The rest of the electromagnetic radiation that is not absorbed and reflected is the cast part: Solar radiation energy reaching the ground = reflected energy + absorbed energy + transmitted energy.
