Diffraction Spectroscope, Pocket Grating Gemological Spectrometer for Quick Gemstone Identification and GIA Use

Product Description Detect the absorption of spectra it is use to view the color of a gemstone, either by shining a light (pen-torch) through the stone into the spectroscope if the stone is transparent, or by viewing its reflected light if the stone is opaque. Inside is a pattern of lines that you must learn to recognize, it is a spectrum (rainbow) of which might be interrupted with black or white lines. 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. A spectroscope will show you the wavelengths of light emitted or reflected from a gem Made of Aluminum and Raster type. Lightweight and durable for use. Compact, pocket size makes it great for traveling, vacations, or to trade shows.
