KEY STRENGTHS:
This handy piece of equipment is perhaps the most important tool in gemology, spectroscope breaks up the light being transmitted from a gemstone into its spectral colors, which allows the gemologist to see the various wavelengths that are being absorbed by the gemstone. Thereby allowing the gemologist to know what elements are contained in the gemstone that causes the absorption. Making this one of the most important tools in identifying gemstones.
Elements within a gemstone will absorb certain levels of energy. And light is energy. Therefore certain elements in a gemstone will absorb certain colors of light based on what energy level they are absorbing. The spectroscope allows us to see which color of light, or energy, is being absorbed, thereby allowing us to know what elements are in a gemstone. This, in turn, allows us to know more about the gemstone, like their identification, where it came from, what causes it to have color, etc... The prism spectroscope is composed of three optical grade glass prisms in optical contact with each other. Spectroscopes allows you to analyze a loose or mounted stone's spectrum. They help distinguish naturally colored diamonds from those that have been irradiated and help to distinguish natural stones from synthetics by the stone's selective absorption of certain wavelengths.

Spectroscope Buying Guide
In gemology, there are two different types of spectroscopes,
each with its own characteristics.
1. Diffraction grating spectroscope
The diffraction grating spectroscope is based on the
principle of diffraction. Light enters through a narrow slit
and is then diffracted by a thin film of diffraction grating
material. This produces a linear spectrum image with a
generally larger view of the red part than a prism
spectroscope.

2. Prism Spectroscope
The prism spectroscope is based on dispersion. The light
enters through a narrow slit and is then dispersed through a
series of prisms. These models are generally more expensive
than their diffraction type cousins.
Because prism spectroscopes are based on dispersion, the
blue area of the spectrum is more spread out and the red
parts are more condensed than the diffraction grating types.
Inside the prism spectroscope
In conclusion, prism type is better than diffraction type,
because it has a larger and more clear image.
