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.

I'm impressed with the quality and utility of the spectroscope. It's good enough to help me know how interesting spectroscopy is going to be as I learn more.

NO directions not even which end to look through and that's important!! little info on line on this piece and have to read about other similar devices. A play toy at best without some basic knowledge. I'll keep trying by reading forams, asking some friends with more knowledge etc. Disappointed but that might change in time, lots of time!!

Great for the price very accurate with full sized view of spectrum. Identify gemstones with a great tool comparable to Gem- A spectroscope. Professional quality at a decent price this not a toy. Is as good as Gem-A. GIA approved one that goes for double. Great precision optics and shows full spectrum no scale. Great for gemological research and any other purpose. Move back to veiw full spectrum!!! Doesn't have grating lines but is still great.

The grating is not high quality but it works. Unit is sturdy and would be adequate for field work
